怎么样将字符导出到.txt文件？

[Z_L_H]

我想将字符串用txt文件保存下来，怎么办？

[柳晛]

using System.IO;

        public static void FTJL(string 字符串) 
        { 
            string path = @"C:\Documents and Settings\Administrator\桌面\文件名.txt"; 

            if (!Directory.Exists(Path.GetDirectoryName(path))) 
            { 
                Directory.CreateDirectory(Path.GetDirectoryName(path)); 
            } 

            StreamWriter sw = new StreamWriter(path, true); 

            sw.WriteLine(字符串); 

            sw.Close(); 
        }

private void AddlogFile(string Message)
{
StreamWriter W;
DirectoryInfo DirInfo = new DirectoryInfo(Server.MapPath("\\cloud_scorpion"));
Message = DateTime.Now.ToString() + " " + Message + System.Environment.NewLine;
if (DirInfo.Exists == false)
{
Directory.CreateDirectory(Server.MapPath("\\cloud_scorpion"));
}
FileInfo fileinfo = new FileInfo(Server.MapPath("\\cloud_scorpion")+ "\\aaa.txt");
if (fileinfo.Exists == false)
{
W = File.CreateText(Server.MapPath("\\cloud_scorpion")+ "\\aaa.txt");
}
else
{
W = File.AppendText(Server.MapPath("\\cloud_scorpion")+ "\\aaa.txt");
}
W.WriteLine(Message);
W.Close();
}

Dim cmd As OleDb.OleDbDataAdapter = New OleDb.OleDbDataAdapter("select * from 1", conn)
Dim dst As DataSet = New DataSet

Try

Response.ContentEncoding = System.Text.Encoding.Default

For j = 0 To dst.Tables(0).Columns.Count - 1

Response.Write(dst.Tables(0).Rows(i)(dst.Tables(0).Columns(j).ColumnName).ToString)
Response.Write(vbTab)
If j = dst.Tables(0).Columns.Count - 1 Then
Response.Write(vbCrLf)
End If
Next
Next
Response.End()

二、读文件代码片断：
using System;
using System.IO;

public class TestReadFile
{
public static void Main(String[] args)
{
// Read text file C:\temp\test.txt
FileStream fs = new FileStream(@c:\temp\test.txt (这边及一下都是有双引号的), FileMode.Open, FileAccess.Read);
StreamReader sr = new StreamReader(fs);

String line=sr.ReadLine();
while (line!=null)
{
Console.WriteLine(line);
line=sr.ReadLine();
}

sr.Close();
fs.Close();
}
}
三、写文件代码：
using System;
using System.IO;

public class TestWriteFile
{
public static void Main(String[] args)
{
// Create a text file C:\temp\test.txt
FileStream fs = new FileStream(@c:\temp\test.txt , FileMode.OpenOrCreate, FileAccess.Write);
StreamWriter sw = new StreamWriter(fs);
// Write to the file using StreamWriter class
sw.BaseStream.Seek(0, SeekOrigin.End);
sw.WriteLine( First Line );
sw.WriteLine( Second Line);
sw.Flush();
}
}
四、拷贝文件：
using System;
using System.IO;

class TestCopyFile
{
public static void Main()
{
File.Copy(c:\\temp\\source.txt, C:\\temp\\dest.txt );
}
}
五、移动文件：
using System;
using System.IO;

class TestMoveFile
{
public static void Main()
{
File.Move(c:\\temp\\abc.txt, C:\\temp\\def.txt );
}
}
[/CODE]

[code=C#]
C#导出txt文件
//导成txt
Response.Clear();
Response.Buffer = false;
Response.ContentEncoding = System.Text.Encoding.UTF8;
Response.AppendHeader("Content-Disposition", "attachment;filename=" + Server.UrlEncode(fileName) + ".txt");
Response.ContentType = "text/plain";
this.EnableViewState = false;
Response.Write(sb.ToString());
Response.End();

//导成excel
Response.Clear();
Response.Buffer = false;
Response.Charset = "GB2312";
//Response.ContentEncoding = System.Text.Encoding.UTF8;
Response.AppendHeader("Content-Disposition", "attachment;filename=aa.txt");
Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");
//Response.ContentType = "application/ms-excel";
Response.ContentType = "text/plain";
this.EnableViewState = false;
// System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
//System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
//this.GridView1.RenderControl(oHtmlTextWriter);
Response.Write("sdfasdfasdfasdfasdfasdfasdfasdfadf");
Response.End();

你了解一下System.IO命名空间里面的类，很简单的
