c# – streamWriter重写文件或附加到文件

我在用这个

for($number=0; $number < 5; $number++){
StreamWriter x = new StreamWriter("C:\\test.txt");
                x.WriteLine(number);
                x.Close();

}

如果某些内容在test.text中,则此代码将不会覆盖它.我有2个问题

1: how can I make it overwrite the file
2: how can I append to the same file

使用C#

解决方法

尝试FileMode枚举器：

FileStream fappend = File.Open("C:\\test.txt",FileMode.Append); // will append to end of file

        FileStream fcreate = File.Open("C:\\test.txt",FileMode.Create); // will create the file or overwrite it if it already exists
