c# - 从字符串中删除单个空格

Question

"How do I do this?              "

假设我有这个字符串。如何从末尾只删除一个空格？下面显示的代码给我一个错误，说计数超出范围。

string s = "How do I do this?              ";
s = s.Remove(s.Length, 1);

Answer 1

您只需要改用它:

string s = "How do I do this?              ";
s = s.Remove(s.Length-1, 1);

如前所述here :

Remove(Int32) Returns a new string in which all the characters in the currentinstance, beginning at a specified position and continuing through thelast position, have been deleted.

在数组中，位置范围从 0 到 Length-1，因此会出现编译错误。
