string s = "Hello   World";

推荐答案

Trim仅删除前导字符和尾随字符.

如果要删除中间的一个，请使用替换，例如

s.Replace(" ",String.Empty);

在代码行中，我们在String的任何位置都用空格char和空字符串char替换了.

Trim only removes leading and trailing chars.

If you want to remove the one in the middle also then use replace, e.g.

s.Replace(" ",String.Empty);

in the line of code, we are replacing a Space char with and empty string char, in any position of String s.

您误解了方法Trim，

Trim 方法仅删除所有前导和尾随空格，而不会从中间删除.

要完成您的解决方案，您可以使用Replace Method
即

You are misunderstanding the method Trim,

Trim method only removes all leading and trailing whitespace, It doesn''t remove from the middle.

for accomplish your solution you can use Replace Method
i.e

s.Replace(" ","");

这将为您提供所需的输出.

来自MSDN ， String.Trim方法 [

From MSDN, String.Trim Method[^]:

Trim()从当前String对象中删除所有前导和尾随空格字符.

Trim() Removes all leading and trailing white-space characters from the current String object.

那么，您认为预期的输出是多少?
