使用LINQ从字符串中删除后缀如果列表中包含后缀？

如何解决使用LINQ从字符串中删除后缀如果列表中包含后缀？

| 如何使用C＃/ LINQ从字符串中去除后缀并返回？例：

string[] suffixes = { \"Plural\",\"Singular\",\"Something\",\"SomethingElse\" };

string myString = \"DeleteItemmessagePlural\";

string stringWithoutSuffix = myString.???; // what do I do here?

// stringWithoutSuffix == \"DeleteItemmessage\"

    

解决方法

        

var firstMatchingSuffix = suffixes.Where(myString.EndsWith).FirstOrDefault();
if (firstMatchingSuffix != null)
    myString = myString.Substring(0,myString.LastIndexOf(firstMatchingSuffix));

    ,        您需要从列表中构建一个正则表达式：

var regex = new Regex(\"(\" + String.Join(\"|\",list.Select(Regex.Escape)) + \")$\");

string stringWithoutSuffix = regex.Replace(myString,\"\");

    ,        

// Assuming there is exactly one matching suffix (this will check that)
var suffixToStrip = suffixes.Single(x => myString.EndsWith(x));

// Replace the matching one:
var stringWithoutSuffix =  Regex.Replace(myString,\"(\" +suffixToStrip + \")$\",\"\");

或者，因为您知道匹配后缀的长度：

// Assuming there is exactly one matching suffix (this will check that)
int trim = suffixes.Single(x => myString.EndsWith(x)).Length;

// Remove the matching one:
var stringWithoutSuffix =  myString.Substring(0,myString.Length - trim);
