C＃控制台输出

Question

Is it possible to control/write to a console from another. I have tested the Console.WriteLine, but nothing happend. I appreciate any help.

I meant write to a console from another class . Sorry for the misleading. I have a server class (Server.cs) and the main class (Program.cs). The server class is going to write some info about connection, and stuff like that, to the console.

To write to the calling console, your application needs to be marked as a Console application in project settings. If you write to the console in a UI application, your process will create a new one and then write in it.

If you want to write to another existing console, I guess it could be possible using P-Invoke on the Win32Api functions such as AttachConsole , WriteConsole and FreeConsole .

If i'm not mistake, you want something like this

System.Diagnostics.Process p = new System.Diagnostics.Process();

p.StartInfo.FileName = "ModelExporter.exe";
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.RedirectStandardInput = true;
p.StartInfo.UseShellExecute = false;
p.StartInfo.CreateNoWindow = true;
p.Start();

StreamReader myStreamReader = p.StandardOutput;

// Reads a single line of the programs output.
string myString = myStreamReader.ReadLine(); 

// This would print the string to the DOS Console for the sake of an example.
// You could easily set a textbox control to this string instead...
Console.WriteLine(myString);

p.Close();
