FileInfo::Create Method ()

 

Creates a file.

Namespace:   System.IO
Assembly:  mscorlib (in mscorlib.dll)

public:
FileStream^ Create()

Return Value

Type: System.IO::FileStream^

A new file.

By default, full read/write access to new files is granted to all users.

This method is a wrapper for the functionality provided by File::Create.

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();
}

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;
   }
}

//This code produces output similar to the following; 
//results may vary based on the computer/file structure/etc.:
//
//This is some text in the file.
