Question

var myNew = myRegex1.Split(strTargetString);
                    if ((myNew[1].Trim()).Length > 12)
                    {
                       myNew[1]= (myNew[1].Substring(0, 9))+"..";
                    }                        }
                    _model.Add(new ScoresModel()
                    {
                        NameTeam1 = (myNew[1].Trim()),
                        ScoreTeam1 = Convert.ToInt32(myNew[2].Trim()),
                        NameTeam2 = (myNew[3].Trim()),
                        ScoreTeam2 = Convert.ToInt32(myNew[4].Trim()),
                        Round = (myNew[5].Trim()).Substring(1, myNew[5].Length - 2),
                        URL = item.ItemLink
                    });

以上是我的规格。将字符串分成5个部分后。我想对第一个分割的字符串应用一个检查是否长度大于12.如果是，则将其修剪为10个字符并在字符串后面添加“..”（两个点）。 *但在修剪代码后，它在myNew [1]，myNew [2]，myNew [3]，myNew [4]，myNew [5]中给出了以下方法的错误。 *错误为The name myNew does not exist in current context.

_model.Add(new ScoresModel()
                    {
                        NameTeam1 = (myNew[1].Trim()),
                        ScoreTeam1 = Convert.ToInt32(myNew[2].Trim()),
                        NameTeam2 = (myNew[3].Trim()),
                        ScoreTeam2 = Convert.ToInt32(myNew[4].Trim()),
                        Round = (myNew[5].Trim()).Substring(1, myNew[5].Length - 2),
                        URL = item.ItemLink
                    });

我想你想要这个：

var myNew = myRegex1.Split(strTargetString);
                    if ((myNew[0].Trim()).Length > 12)
                    {
                       myNew[0]= myNew[0].Substring(0, 10)+"..";
                    }   
_model.Add(new ScoresModel()
                    {
                        NameTeam1 = (myNew[0].Trim()),
                        ScoreTeam1 = Convert.ToInt32(myNew[1].Trim()),
                        NameTeam2 = (myNew[2].Trim()),
                        ScoreTeam2 = Convert.ToInt32(myNew[3].Trim()),
                        Round = (myNew[4].Trim()).Substring(1, myNew[4].Length - 2),
                        URL = item.ItemLink
                    });

试试这个：

var myNew = myRegex1.Split(strTargetString);
_model.Add(new ScoresModel()
{
    NameTeam1 = myNew[0].Trim().Length > 12 ? myNew[0].Trim().Substring(0, 9)+".." : myNew[0].Trim(),
    ScoreTeam1 = Convert.ToInt32(myNew[1].Trim()),
    NameTeam2 = myNew[2].Trim(),
    ScoreTeam2 = Convert.ToInt32(myNew[3].Trim()),
    Round = myNew[4].Trim().Substring(1, myNew[4].Trim().Length - 2),
    URL = item.ItemLink
});

拆分结果为0索引;）像这样，你不设置数组的第一个元素，只需使用它。

使用Trim测试字符串时要小心，如果以后不使用它（对于子字符串），如果字符串以空格开头，则可能会出错。

分裂之后，我希望在分割字符串的长度上有条件
