That code is C++ code. Are you trying to convert that to C#?

That code is opening a file each time a key is pressed. That seems innefficient. Since this is only a small part of the program, I probably misunderstand but based on what I see the file should not be opened at that time.

I do not understand "execute exe of this sdk code through c#". Do you mean that you are executing the unmanaged C++ program from C# but the C++ program is not working? How are you executing the C++ program?

Hi,

If you write some content into the file then, (include System.IO namespace)

string str = "Hi! How are you?";
//Write the data into file.
FileStream fileStream = new FileStream(@"c:\type.txt", FileMode.Append, FileAccess.Write);
StreamWriter streamWriter = new StreamWriter(fileStream);
streamWriter.Write(str);
streamWriter.Close();
fileStream.Close();

If you want to open the same file after this content written into file then
System.Diagnostics.Process.Start(@"c:\Test.txt");
