中的后缀'le'，ana，'go'等等。具体如何做到这一点取决于你想要做什么。

但是......如果我们假设你有一个返回起始索引的后缀查找方法，则它非常简单：

 List< string> noSuffixes = withSuffixes.Select（s = >  s.Substring（ 0 ，GetIndexOfSuffix（s））。 ToList（）; < /   string  > 跨度> 

I have list of item
after matching the suffixes from suffix containing file.
The problem is that i can't remove the suffixes from the word in list item. Is there any method to remove the suffixes in C#
example i have follow list
[0]apple
[1]cat
[2]banana
[3]mango
and so on

i want to remove suffixes 'le',ana, 'go' etc in c#

Exactly how you would do this would depend on exactly what you are trying to do.
But...if we assume you have a suffix finding method that returns the starting index then it's pretty trivial:

List<string> noSuffixes = withSuffixes.Select(s => s.Substring(0, GetIndexOfSuffix(s)).ToList();</string>
