一個新檔案。

範例

以下範例建立一個檔案的參考，然後使用 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();
    }
}

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

以下範例建立一個檔案，加入一些文字，然後從檔案中讀取。

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.

Imports System.IO
Imports System.Text

Public Class Test

    Public Shared Sub Main()
        Dim path As String = "c:\temp\MyTest.txt"
        Dim fi As FileInfo = New FileInfo(path)

        ' Delete the file if it exists.
        If fi.Exists() Then
            fi.Delete()
        End If

        'Create the file.
        Dim fs As FileStream = fi.Create()
        Dim info As Byte() = New UTF8Encoding(True).GetBytes("This is some text in the file.")

        'Add some information to the file.
        fs.Write(info, 0, info.Length)
        fs.Close()

        'Open the stream and read it back.
        Dim sr As StreamReader = fi.OpenText()

        Do While sr.Peek() >= 0
            Console.WriteLine(sr.ReadLine())
        Loop
        sr.Close()
    End Sub
End Class

'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.
