execute dumpbin.exe from C# app

Hello, im trying to call dumpbin.exe from C# app and capture result back in my app for future processing, but im stuck ... :(

my attempts:

attempt #1:

Process.Start(@"C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\bin\dumpbin.exe", "/exports LIB.dll")

result: mspdb110.dll not found

attempt #2:

var cmd = Process.Start("cmd.exe /C \"c:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\Tools\VsDevCmd.bat\"");
cmd.WaitForExit();
Process.Start(@"C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\bin\dumpbin.exe", "/exports LIB.dll");

result: same as #1

attempt #3

string temp = Path.GetTempFileName();
string bat = Path.ChangeExtension(temp, ".bat");
File.WriteAllLines(bat, new[] {
    @"call ""c:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\Tools\VsDevCmd.bat""","dumpbin.exe /exports \"" + dll + "\" >> \"" + temp + "\""
});
ProcessStartInfo info = new ProcessStartInfo {
    FileName = "cmd.exe",
    Arguments = "/C \"" + bat + "\"",                
    CreateNoWindow = true
};
Process.Start(info).WaitForExit();

foreach (var line in File.ReadLines(temp)) {
    Console.WriteLine(line);
}

result: temp file contains requested data ... but it is FILE :(

attempt #4: 

string temp = Path.GetTempFileName();
string bat = Path.ChangeExtension(temp, ".bat");
File.WriteAllLines(bat, new[] {
    @"call ""c:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\Tools\VsDevCmd.bat""","dumpbin.exe /exports \"" + dll + "\""
});
ProcessStartInfo info = new ProcessStartInfo {
    FileName = "cmd.exe",
    Arguments = "/C \"" + bat + "\"",      
    RedirectStandardOutput = true,
    UseShellExecute = false,
    CreateNoWindow = true
};
var proc = Process.Start(info);
proc.WaitForExit();
var data = proc.StandartOutput.ReadToEnd();

result: process proc never exits ...

attempt #5: no new ideas ... going here :) .... so my question is this:

Is there a way to accomplish this without generating temp files?

Cheers
