列表列表的列表

Question

我有一个C#List of sting,可以是x行长.下面将显示一个小例子.我想知道我现在将如何获得小的不同列表,以便A不会出现多次.这个列表即将推出代码.所以它是随机的.

list = {a,b,a,f,a,null,a,e,a,e}

Answer 1

尝试LINQ ....更具体一点......鉴于你的列表实际上是字符串[],你可以这样做......

string[] list = {"a","b","a","f","a",null,"a","e","a","e"};
var distinctList = list.Distinct();

foreach (var str in distinctList)//Distinct list of values
{
    Console.Write(str); 
}
