Create file

In this tutorial we will see how to create text file. .NET framework provides few classes to deal with file operation all these classes are available under System.IO namespace.

Let's create text file

using C# code sample. in this example we have use FileStream to create File and StreamWriter class to write content into newly created file.

FileStream fileStream = new FileStream(@"c:\myFile.txt", FileMode.OpenOrCreate);
StreamWriter MyStreamWriter = new StreamWriter(fileStream);
try
{
MyStreamWriter.Write("This is my first line");
MyStreamWriter.Write("This is my Second line");
}
catch (Exception ex)
{
throw ex;
}
finally
{
MyStreamWriter.Flush();
MyStreamWriter.Close();
}

Using vb.net Sample

Dim fileStream As New FileStream("c:\myFile.txt", FileMode.OpenOrCreate)
Dim MyStreamWriter As New StreamWriter(fileStream)
Try 
MyStreamWriter.Write("This is my first line") 
MyStreamWriter.Write("This is my Second line") 
Catch ex As Exception 
Throw ex 
Finally 
MyStreamWriter.Flush() 
MyStreamWriter.Close() 
End Try
