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 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.
        // Delete the file.

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

using System;
using System.IO;
using System.Text;

class Test 

    public static void Main() 
        string path = @"c:\MyTest.txt";
        FileInfo fi = new FileInfo(path);

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

        //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) 
//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.
