你把值取出来然后往里写不久完事了 下面的代码示例显示向文本文件写入文本的简单方法。 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); } } }下面的代码示例创建一个新文本文件并向其写入一个字符串。 using System; using System.IO; public class TextToFile { private const string FILE_NAME = "MyFile.txt"; public static void Main(String[] args) { if (File.Exists(FILE_NAME)) { Console.WriteLine("{0} already exists.", FILE_NAME); return; } StreamWriter sr = File.CreateText(FILE_NAME); sr.WriteLine ("This is my file."); sr.WriteLine ("I can write ints {0} or floats {1}, and so on.", 1, 4.2); sr.Close(); } } public static WriteTextFile(string logMessage) { if (logMessage!=null && logMessage.Length>0) { System.IO.StreamWriter w = System.IO.File.AppendText("logServer.txt"); w.WriteLine("记录时间:{0}", DateTime.Now.ToString()); w.WriteLine("信息文本:{0}", logMessage); w.WriteLine("---------------------------------------------------------------------------------------------"); w.Flush(); w.Close(); } }
下面的代码示例显示向文本文件写入文本的简单方法。
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);
}
}
}下面的代码示例创建一个新文本文件并向其写入一个字符串。
using System;
using System.IO;
public class TextToFile
{
private const string FILE_NAME = "MyFile.txt";
public static void Main(String[] args)
{
if (File.Exists(FILE_NAME))
{
Console.WriteLine("{0} already exists.", FILE_NAME);
return;
}
StreamWriter sr = File.CreateText(FILE_NAME);
sr.WriteLine ("This is my file.");
sr.WriteLine ("I can write ints {0} or floats {1}, and so on.",
1, 4.2);
sr.Close();
}
}
public static WriteTextFile(string logMessage)
{
if (logMessage!=null && logMessage.Length>0)
{
System.IO.StreamWriter w = System.IO.File.AppendText("logServer.txt"); w.WriteLine("记录时间:{0}", DateTime.Now.ToString());
w.WriteLine("信息文本:{0}", logMessage);
w.WriteLine("---------------------------------------------------------------------------------------------");
w.Flush();
w.Close();
}
}
private const string FILE_NAME = "11.txt";
public void WriteFile()
{
string str = textBox1.Text;
StreamWriter sr;
if (File.Exists(FILE_NAME)) //如果文件存在,则创建File.AppendText对象
{
//sr = File.AppendText(FILE_NAME);
}
else //如果文件不存在,则创建File.CreateText对象
{
sr = File.CreateText(FILE_NAME);
sr.WriteLine(str);
sr.Close();
}
}
