推荐答案

您可以使用 string.TrimStart 并传入您要删除的字符:

You could use string.TrimStart and pass in the characters you want to remove:

var result = yourString.TrimStart('-', '_');

但是，这仅是一个好主意，如果您要删除的特殊字符的数目众所周知且很小.
如果不是这种情况，则可以使用正则表达式:

However, this is only a good idea if the number of special characters you want to remove is well-known and small.
If that's not the case, you can use regular expressions:

var result = Regex.Replace(yourString, "^[^A-Za-z0-9]*", "");
