我有一个本地文件路径包含，我需要改变所有出现的/为远程文件的路径。

I have a local file path containing "" and I need to change all occurrences to "/" for a remote file path.

我已经试过

myString.replace("","/")

和

myString.replace(Convert.ToChar(92), Convert.ToChar(47)) 

似乎都留在机智的..

Both seem to leave the "" in tact..

答：

NewString = myString.replace("","/")

但问题是，我没有它赋值给一个变量。逃脱斜线实际上是由它失败了，在vb.net中最少。

The problem was that I was not assigning it to a variable. Escaping the slash actually made it fail, in vb.net at least.

推荐答案

字符串是不可变的。该替换方法返回一个新字符串，而不是影响当前字符串，因此，你需要捕获结果的变量。如果你使用VB.NET没有必要逃避反斜杠，但在C＃中，必须通过他们的使用2转义。

Strings are immutable. The Replace method returns a new string rather than affecting the current string, therefore you need to capture the result in a variable. If you're using VB.NET there's no need to escape the backslash, however in C# it must be escaped by using 2 of them.

VB.NET（没有逃脱需要）：

VB.NET (no escaping needed):

myString = myString.Replace("","/")

C＃（反斜杠转义）：

C# (backslash escaped):

myString = myString.Replace("","/");

我假设你正在使用VB.NET，因为你不包括分号，也没有逃脱反斜杠，并且由于使用的替代方法的外壳。

I assume you're using VB.NET since you don't include a semicolon, didn't escape the backslash and due to the casing of the replace method used.
