C# 将内容写入txt文档

<1>  FileStream fs = new FileStream(@"D:\text.txt", FileMode.Append);

StreamWriter sw = new StreamWriter(fs, Encoding.Default);

sw.Write(strAnalasy);

sw.Close();

fs.Close();

<2>  FileStream TreatProcess = new FileStream(@"文件目录", FileMode.Append);

TreatProcess.Write(receiveData, i + 2, 4);

TreatProcess.Close();

稳定的写入txt文件的方式：

FileStream fs = new FileStream("zhanglei.txt", FileMode.Create);

byte[] data = System.Text.Encoding.Default.GetBytes("a" + System.Environment.NewLine +"b");

fs.Write(data, 0, data.Length);

fs.Flush();

fs.Close();

稳定的读txt文档的方式:

StreamReader sr = new StreamReader("zhanglei.txt", Encoding.Default);

string line = null;

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

{

MessageBox.Show(line);

}

sr.Close();
