这样的事情可能会起到作用：

Somthing like this might do the job:

private string CellCombination(IEnumerable<string> values)
{
	string result = "";
	foreach (string s in values)
	{
		if (!string.IsNullOrWhiteSpace(s)) result += string.Format("{0},", s);
	}

	return result.Trim(',');

}</string>

或者使用Linq同样的事情

Or the same thing using Linq

private string CellCombination(IEnumerable<string> values)
{
    string result = values.Where(s => !string.IsNullOrWhiteSpace(s)).Aggregate("", (current, s) => current + string.Format("{0},", s));

    return result.Trim(',');

 }

要使用它，只需将您的单元格作为可枚举集合传入函数。



所以这样的事情：

To use it, just pass in your cells into the function as an enumerable collection.

So something like this:

e.Row.Cells[1].Text = CellCombination(new [] {e.Row.Cells[1].Text, e.Row.Cells[2].Text, e.Row.Cells[3].Text });

e.Row.Cells[1].Text = e.Row.Cells[1].Text + (string.IsNullOrEmpty(e.Row.Cells[2].Text) ? string.empty : ",") + e.Row.Cells[2].Text + (string.IsNullOrEmpty(e.Row.Cells[3].Text) ? string.empty : ",") + e.Row.Cells[3].Text;

e.Row.Cells[1].Text = e.Row.Cells[1].Text + ((e.Row.Cells[2].Text.ToString().Trim().Length>0)?  ("," + e.Row.Cells[2].Text) : string.Empty )+  ((e.Row.Cells[3].Text.ToString().Trim().Length>0) ?  ("," + e.Row.Cells[3].Text) : string.Empty );
