推荐答案
问题是你将两种字符串形式合二为一:
The problem is that you are using both string forms in one:
string path = @"D:\ \Yourfile.txt";
用其中一个替换它可以解决你的问题:
Replacing that with one of these should cure your problem:
string path = @"D:\Yourfile.txt";
或
Or
string path = "D:\\Yourfile.txt";
但是......这是一个非常糟糕的方法!
首先要更有效地做到这一点:
But...that's a very bad way to do it!
Start by doing that more efficiently:
if (File.Exists(path)) givenText = File.ReadAllText(path);
然后在一个中使用StreamWriter 使用
块
或者,用以下方法替换整个方法:
and then use the StreamWriter in a using
block
Alternatively, replace the whole method with this:
private void pageload()
{
File.AppendAllText(@"D:\YourFile.txt", "la la la ala" + Environment.NewLine);
}
