For eg. creating/deleting a file using edit myfile.txt command

C#

System.Diagnostics.Process proc = new System.Diagnostics.Process();
              proc.EnableRaisingEvents = false;
              string strCmdLine;
              strCmdLine = "edit kiran.txt";
              System.Diagnostics.Process.Start("CMD.exe", strCmdLine);

but in above code only command prompt is getting opened.i cant able to create a file.

Why don't you use the built-in .NET libraries to create this text file?

There is no "DOS" to be control of. If you really insist that you want to do this, this way, then you would need to take a look at the Process.StandardInput property

Of course, but I don't see a need for this in this case -- OP uses command line, just incorrectly.
The problem is using unwanted "CMD.EXE". I answered, please see.

There is no need at all.

I updated the commend and my answer. It's about "CMD.EXE".

This is .NET. On all systems which can host .NET, there is no such thing as "DOS", period.

By the way, what's "edit" and why using it? Executing a separate process is always bad; the processes are well isolated. Wes is right.

EDIT, the EdLin's successor.

Anyway, please see my solution.

First, please see my comment to the question: in the scope of it, there is no such thing as "DOS". (And that was a root cause of your mistake.)

Now, to fix your problem you just need to understand that you don't need "CMD.EXE". This is nothing but yet another program which is irrelevant to the problem you are trying to solve: starting an application.

So, all you need is this:

C#

string app = "edit";
string strCmdLine = "kiran.txt";
System.Diagnostics.Process.Start(app, strCmdLine);

Now, I don't know what is "edit", but is this is some text editor, chances are, you don't really want to start it; it won't be able to collaborate with your application. It would be more reasonable to create a UI application (WPF or System.Windows.Forms) and embed a simple edit control like TextBox in your application.

+5. Probably overkill for what the OP wants, but a very good find nonetheless.
