.NET寫入文本文件的操作淺析
.NET寫入文本文件的操作是如何實(shí)現(xiàn)的呢?下面我們通過使用VB和C#兩種代碼示例向你演示如何實(shí)現(xiàn)寫入文本文件的操作細(xì)節(jié),希望對(duì)你了解寫入文本文件有所幫助
***個(gè)示例演示如何向現(xiàn)有文件中添加文本。第二個(gè)示例演示如何創(chuàng)建一個(gè)新文本文件并向其中寫入一個(gè)字符串。 WriteAllText 方法可提供類似的功能。
.NET寫入文本文件的操作時(shí)需要注意注意
  
Visual Basic 用戶可以選擇使用由 My.Computer.FileSystem 對(duì)象提供的方法和屬性進(jìn)行文件 I/O。有關(guān)更多信息,請(qǐng)參見 My.Computer.FileSystem 對(duì)象。
.NET寫入文本文件的操作示例Visual Basic實(shí)現(xiàn)添加文本
- Imports System
 - Imports System.IO
 - Class Test
 - Public Shared Sub Main()
 - ' Create an instance of StreamWriter to write text to a file.
 - Using sw As StreamWriter = New StreamWriter("TestFile.txt")
 - ' Add some text to the file.
 - sw.Write("This is the ")
 - sw.WriteLine("header for the file.")
 - sw.WriteLine("-------------------")
 - ' Arbitrary objects can also be written to the file.
 - sw.Write("The date is: ")
 - sw.WriteLine(DateTime.Now)
 - sw.Close()
 - End Using
 - End Sub
 - End Class
 
.NET寫入文本文件的操作示例C#實(shí)現(xiàn)添加文本
- using System;
 - using System.IO;
 - class Test
 - {
 - public static void Main()
 - {
 - // Create an instance of StreamWriter to write text to a file.
 - // The using statement also closes the StreamWriter.
 - using (StreamWriter sw = new StreamWriter("TestFile.txt"))
 - {
 - // Add some text to the file.
 - sw.Write("This is the ");
 - sw.WriteLine("header for the file.");
 - sw.WriteLine("-------------------");
 - // Arbitrary objects can also be written to the file.
 - sw.Write("The date is: ");
 - sw.WriteLine(DateTime.Now);
 - }
 - }
 - }
 
.NET寫入文本文件的操作示例Visual Basic實(shí)現(xiàn)寫入一個(gè)字符串
- Option Explicit On
 - Option Strict On
 - Imports System
 - Imports System.IO
 - Public Class TextToFile
 - Private Const FILE_NAME As String = "MyFile.txt"
 - Public Shared Sub Main()
 - If File.Exists(FILE_NAME) Then
 - Console.WriteLine("{0} already exists.", FILE_NAME)
 - Return
 - End If
 - Using sw As StreamWriter = File.CreateText(FILE_NAME)
 - sw.WriteLine("This is my file.")
 - sw.WriteLine("I can write ints {0} or floats {1}, and so on.", 1, 4.2)
 - sw.Close()
 - End Using
 - End Sub
 - End Class

 - }
 
.NET寫入文本文件的操作示例的基本實(shí)現(xiàn)就向你介紹到這里,希望對(duì)你了解.NET寫入文本文件的操作有所幫助。
