在string.Split（）之後的任何更好的方法來TRIM（）？

Question

注意到一些代碼，如

string[] ary = parms.Split(",".ToCharArray(), StringSplitOptions.RemoveEmptyEntries); 
for(int i = 0; i < ary.Length; i++) 
     ary[i] = ary[i].Trim(); 

工作正常，但不知道是否有更好的方法來做到這一步

Answer 1

string[] trimmedStrings = parms.Split(',') 
           .Select(s => s.Trim()) 
           .Where(s => s != String.Empty) 
           .ToArray(); 

順便說一句，可以考慮使用像List<string>而不是傳統陣列的通用類型化列表

IList<string> trimmedStrings = parms.Split(',') 
            .Select(s => s.Trim()) 
            .Where(s => s != String.Empty) 
            .ToList(); 

Answer 2

儘管如此2的步驟，但不循環

ary = ary.Select(str => str.Trim()).ToArray(); 

或

ary = ary.Split(',').Select(str => str.Trim()) 
        .Where(str => str != string.Empty) 
        .ToArray(); 

爲了保持RemoveEmptyEntries行爲，並刪除那些trimable

Answer 3

這確實是非常整齊的項目：

//This could be inlined to the row below if you wanted 
Regex oRE = new Regex(@"\s*\,\s*"); 
string TestString = ",, test , TEST 2 ,Test3"; 
//This is really the line you're looking for - the rest of the code just sets up an example 
string[] Results = oRE.Split(TestString.Trim()); 
foreach(string S in Results){ 
    Console.WriteLine(">>" + S + "<<"); 
} 

爲一個班輪：

string[] Results = new Regex(@"\s*\,\s*").Split(TestString.Trim());
