string path;

path=@Application.StartupPath+"//log//log"+DateTime.Now.ToString("yyyy-MM--dd hhmmss")+".txt";

StreamWriter sw=File.CreateText(path);

sw.Write("hello");

sw.WriteLine("hello");

sw.Close();

读取文本

string str;

string address="";

FileStream fs;

string path;

path=Application.StartupPath+"//log//"+"1.txt";

try

{

fs=new FileStream(path,FileMode.OpenOrCreate);

}

catch(FileNotFoundException ex)

{

MessageBox.Show("读取文件出现错误!"+ex.Message,"错误",0x00);

return;

}

StreamReader sr=new StreamReader(fs);

while((str=sr.ReadLine())!=null)

{

address=address+str;

}

sr.Close();
