Answer 1

using System.IO;

sw.Close();

Answer 2

System.IO.StreamWriter wt = new System.IO.StreamWriter();
            wt.Write("0");
            wt.Close();

Answer 3

// 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("0");
            sw.Close();
        }

Server.Path(".")

谢谢,搞定了
public class Class1:System.Web.UI.Page
{
public Class1()
{
//
// TODO: 在此处添加构造函数逻辑
//
} public void NewFile(string  FileName) 
{

String path=Server.MapPath(".")+"TxtFile\\"+FileName+".txt";
StreamWriter sw=new StreamWriter(path);
sw.WriteLine("0");
sw.Close();
} }
