FileInfo.Create Method
Creates a file.
Namespace: System.IO
Assembly: mscorlib (in mscorlib.dll)
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. fs.Close(); // Delete the file. fi.Delete(); } }
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) { 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); } } } } //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.
