这是基于我刚刚解决的一个测试的一点贡献，可能对这里其他顶级贡献者的改进有所帮助。 以下是我所做的事情:

I used OrderBy which allows me order or sort the items from smallest to the highest using LINQ I then convert it to back to an array and then re-assign it back to the primary datasource So i then initialize j which is my right hand side of the array to be 1 and i which is my left hand side of the array to be 0, i also initialize where i would i to stop to be 0. I used a while loop to increment through the array by going from one position to the other left to right, for each increment the stop position is the current value of i + 2 which i will use later to truncate the duplicates from the array. I then increment by moving from left to right from the if statement and from right to right outside of the if statement until i iterate through the entire values of the array. I then pick from the first element to the stop position which becomes the last i index plus 2. that way i am able to remove all the duplicate items from the int array. which is then reassigned.

int size = a.Length;
        for (int i = 0; i < size; i++)
        {
            for (int j = i + 1; j < size; j++)
            {
                if (a[i] == a[j])
                {
                    for (int k = j; k < size; k++)
                    {
                        if (k != size - 1)
                        {
                            int temp = a[k];
                            a[k] = a[k + 1];
                            a[k + 1] = temp;

                        }
                    }
                    j--;
                    size--;
                }
            }

strINvalues = "1,1,2,2,3,3,4,4";
strINvalues = string.Join(",", strINvalues .Split(',').Distinct().ToArray());
Debug.Writeline(strINvalues);

不确定这是巫术还是漂亮的代码

1 strINvalues .Split('，').Distinct().ToArray()

2字符串。加入(”、“XXX);

1拆分数组，使用Distinct [LINQ]删除重复项 2 .在没有副本的情况下将其连接回去。

抱歉，我从来没有读过StackOverFlow上的文本，只是代码。它比文本更有意义;)
