用Linq快速删除重复的元素的方法

实现代码如下：

private
void button8_Click(object sender, EventArgs e) 

{

    string[] myStrs
= { "lihao","lixiaodaoaaa","lili","meinv","lixiaodaoaaa","geili"

                          ,"sb","nihao","sunray","sss","lihao","geilideren","bushihaoren"

                          ,"sunrrr","sunray","nishuone","ceshi"};

    IEnumerable<string> strNames
= myStrs.Distinct().OrderBy(p=>p.Length);

    foreach (string str
in strNames)

    {

        listBox1.Items.Add(str);

    }

}

private
void button7_Click(object sender, EventArgs e) 

{

    string[] myStrs
= { "lihaoDaniu",
"lixiaodaoahenniubi", "nimeimeiLoveYou",
"iloveyousb", "good",
"giveme"

                          , "loveeeeeeeeeeeeeeeeee",
"shaa","bushi","String","liulongq","libo","hanleilei"

                          ,"nishi","geilibam","aobabaM","cheerUp","chili","zicox","zicoxNiubi","sunrayTest"

                      ,"henhao","nihao","woshiGehaoren","good","shabi","test","myString","loveLe","geili"};

    string myLen
= myStrs.Length.ToString();

    MessageBox.Show(myLen);

    IEnumerable<string> myName
= myStrs.Concat(myStrs);

    String str = myName.Count().ToString();

    MessageBox.Show("连接后的字符串长度"
+ str);

    IEnumerable<string> strAferDistinct
= myName.Distinct();

    string strN
= strAferDistinct.Count().ToString();

    MessageBox.Show("删除重复的元素后字符串长度为"
+ strN);

}
