FileInfo.Create Method

public:
 System::IO::FileStream ^ Create();

public System.IO.FileStream Create();

member this.Create : unit -> System.IO.FileStream

Public Function Create () As FileStream

A new file.

The following example creates a reference to a file, and then creates the file on disk using FileInfo.Create().

using namespace System;
using namespace System::IO;
int main()
{
   
   // Create a reference to a file.
   FileInfo^ fi = gcnew FileInfo( "temp.txt" );
   
   // Actually create the file.
   FileStream^ fs = fi->Create();
   
   // Modify the file as required, and then close the file.
   fs->Close();
   
   // Delete the file.
   fi->Delete();
}

using System;
using System.IO;

public class DeleteTest
{
    public static void Main()
    {
        // Create a reference to a file.
        FileInfo fi = new FileInfo("temp.txt");
        // Actually create the file.
        FileStream fs = fi.Create();
        // Modify the file as required, and then close the file.
        fs.Close();
        // Delete the file.
        fi.Delete();
    }
}

Imports System.IO

Public Class DeleteTest
    Public Shared Sub Main()
        ' Create a reference to a file.
        Dim fi As New FileInfo("temp.txt")
        ' Actually create the file.
        Dim fs As FileStream = fi.Create()
        ' Modify the file as required, and then close the file.
        fs.Close()
        ' Delete the file.
        fi.Delete()
    End Sub
End Class

The following example creates a file, adds some text to it, and reads from the file.

using namespace System;
using namespace System::IO;
using namespace System::Text;

int main()
{
   String^ path = "c:\\MyTest.txt";
   FileInfo^ fi = gcnew FileInfo( path );
   
   // Delete the file if it exists.
   if ( fi->Exists )
   {
      fi->Delete();
   }
   
   //Create the file.
   FileStream^ fs = fi->Create();
   try
   {
      array<Byte>^info = (gcnew UTF8Encoding( true ))->GetBytes( "This is some text in the file." );
      
      //Add some information to the file.
      fs->Write( info, 0, info->Length );
   }
   finally
   {
      if ( fs )
         delete (IDisposable^)fs;
   }

   //Open the stream and read it back.
   StreamReader^ sr = fi->OpenText();
   try
   {
      String^ s = "";
      while ( s = sr->ReadLine() )
      {
         Console::WriteLine( s );
      }
   }
   finally
   {
      if ( sr )
         delete (IDisposable^)sr;
   }
}

        // Delete the file if it exists.
        if (fi.Exists)
        {
            fi.Delete();
        }

        //Create the file.
        using (FileStream fs = fi.Create())
        {
            Byte[] info =
                new UTF8Encoding(true).GetBytes("This is some text in the file.");

            //Add some information to the file.
            fs.Write(info, 0, info.Length);
        }

        //Open the stream and read it back.
        using (StreamReader sr = fi.OpenText())
        {
            string s = "";
            while ((s = sr.ReadLine()) != null)
            {
                Console.WriteLine(s);
            }
        }
    }
}
