Have C# main program EXE and multiple C# class library DLLs.
Wish to pass delegate [for callback from DLL to EXE] and common class object to each DLL constructor.
What is the proper C# syntax for that?
EXE has public class, e.g.:

namespace X{  public class y  {    int z;  }}

EXE has instance of that public class.
But how, in DLL source, do I declare that public class?
If I put the same above source in both EXE and DLL, Visual Studio generates syntax error when compiling EXE statement that instantiates the DLL; Visual Studio knows namespace and public class are identical but come from different sources and Visual Studio objects to that.
So how to declare one common public class and make that available to all DLLs when DLLs are instantiated?
Thanks.

Hi Team,

App.Config file key: 

<add key="ProcessTimeInterval" value="14:30"/>  <!--Process Time Interval is in HH:mm in 24 hour time format-->

Class file code:

  var ProcessDateTime = DateTime.ParseExact(ConfigurationValues.ProcessTimeInterval, "HH:mm", null, System.Globalization.DateTimeStyles.None);

I have a config key with excepted time format is "HH:mm".  I am facing issues at var ProcessDateTime  when the config key value is 

Example:
   <add key="ProcessTimeInterval" value="7:30"/>
   <add key="ProcessTimeInterval" value="7:3"/>
   <add key="ProcessTimeInterval" value="7"/>

Need inputs to handle the below scenarios because the below time format is not in "HH:mm".

1) when the config key value is "7:30" format  THEN convert the "7:30"  to  "07:30" in the class file code to make it to "HH:mm" format.

2) when the config key value is "7:3" format  THEN convert the "7:3" to  "07:03" in the class file code to make it to "HH:mm" format.

3) when the config key value is "7" format  THEN  convert the "7" to  "07:00" in the class file code to make it to "HH:mm" format.

How generate textbox dynamically and send values to a row of a datagridview in windows form and c#

Hi,

When i am executing MSBuild I am facing issue "error CS1056: Unexpected character '$' " in the below method.  please provide inputs to use string.Format in the method instead of  $  to solve the issue.

publicstaticstringAdjustHourMinutes(thisstring sender){if(!sender.Contains(":")){return sender.Length==1? $"0{sender}:00": $"{sender}:00";}else{var parts = sender.Split(':');return parts[1].Length==2? $"{Convert.ToInt32(parts[0]):D2}:{parts[1]}":
                    $"{Convert.ToInt32(parts[0]):D2}:0{parts[1]}";}}

Thank you.

hi

i want to define a public read only list of named strings inside a class, something like this;

public enum MyEnum
    {
        string str1 = "str1-value",
        string str2 = "str12-value",
        // ...
    }

I am using C# 4.5 and SQL Server 2014. I wrote a console application which takes 3 file names and folder which is defined in theapp.config file and validates the data and imports the data in SQL Server.

I have given FTP portal to the client, they upload the data and informed me then manually I am running my exe file then data is importing. But I want an automatic process like once the client uploads 3 files in folder my console application auto start.

I thought of using FileSystemWatcher, but here problem is that if put file watcher to folder, create file event, I am getting event when the file is created, this will not work because I need the event when 3 files copied successfully.

This is my app.config file

<appSettings><add key="SourceFolder" value="E:\UploadData" /><add key="ArchiveFolder" value="E:\UploadData\Archive" /><add key="LogFile" value="E:\UploadData\LogFile" /><add key="DisbursementFile" value="xxx_DISB.csv" /> <add key="EmployeeFile" value="xxx_EMP.csv" /><add key="AmountFile" value="xxx_AMT.csv" /></appSettings>

Thanks Best Regard Naweez

i have large xml file which has multiple tables. i want to add one element at specific position. i tried but in my case element is getting added at last which is not desirable.

my tables are. TickerBroker , Broker, BrokerTab and TickerBrokerDateFormatMap

i have multiple Broker element and when i am adding a new Broker then it is getting added in xml fileafter TickerBrokerDateFormatMap element at the end. i want to add Broker element at the end of last Broker element in xml file.

if no Broker element exist in xml file then my added Broker element should be adding at the end of lastTickerBroker element.

here i am giving my sample xml data which is bit big file.

here i am giving my c# code to add xml broker element which is adding at the end of file which is not desirable.

            var zipbrokerrow = xmlDocZip.Descendants().Elements("Broker").FirstOrDefault(b => b.Attribute("ID").Value.ToString().Trim().Equals(broker));

            if (zipbrokerrow != null)
            {

                XElement oSubElm = null;
                XElement brokerelement = new XElement("Broker",
                    new XAttribute("ID", broker),
                    new XAttribute("Ticker_Id", strTicker),

                    new XElement("Broker_Id", strSourceBrokerID));

                foreach (XElement e in zipbrokerrow.Descendants("ALLTabsUnderBroker"))
                {

When users setup displays in Windows a number is assigned to each display and the user can show these numbers by clicking identify. When an application wants to launch a new window I want to show these numbers to the user, to make it easy to select where the window must go. Thus I would like to know what the display number of each monitor is.

I have tried different approaches, using the System.Windows.Forms.Screen.AllScreens which is normally used in C#/.Net to get info about monitor, but it does not contain the number. I also tried using WMI with a series of different "select" statements and a lot of different monitor info can be retrieved, but not the number.

So how do you get the display numbers from Windows or is that impossible?

The numbers I am looking for are the ones shown in this screenshot from Windows 10 (in this case 2 is the primary display):

        {
            Console.WriteLine("2. Async task has started...");
            await GetStringAsync(); // we are awaiting the Async Method GetStringAsync
        }

        static async Task GetStringAsync()
        {
            using (var httpClient = new HttpClient())

                string result = await httpClient.GetStringAsync(URL); //execution pauses here while awaiting GetStringAsync to complete
                //From this line and below, the execution will resume once the above awaitable is done
                //using await keyword, it will do the magic of unwrapping the Task<string> into string (result variable)
                Console.WriteLine("4. The awaited task has completed. Let's get the content length...");
                Console.WriteLine($"5. The length of http Get for {URL}");
                Console.WriteLine($"6. {result.Length} character");
            }
        }

   }).DistinctBy(a => new { a.Section, a.LineItem }).ToList();
}         

I want to update color of row in datagridview based off the row I found in datatable.

foreach (DataRow dr in clsHeartbeat.dtHeartbeat.Rows)
                {
                    DateTime dtNow = DateTime.Now;
                    DateTime dtLastSeen = Convert.ToDateTime(dr["Last Seen"]);
                    double minutes = (dtNow - dtLastSeen).TotalMinutes;
                    if (minutes >= 2)
                    {
                        Console.WriteLine($"  > 2 Minutes  {dr["Machine Name"]}  Last Seen({dr["Last Seen"]}");
                        // Find DataGridView Row and change background color.

Hello,

Actually we(me and my team members) had a debate about differences between interface and abstract classes in oops.Apart from  multiple inheritance what we are achieving by using interface.

Decoupling is one thing.Can any one explain with a real time example. Theoretical definition is not needed.

In real time scenario what we can achieve only thru interface and abstract class.

Its always confusing.I have read many articles so i know the theoretical background.But in real time when we can use interface/abstract class is still a question mark?
