GridView里有一列数据如下
123.23
26.35
58.42
0.00
23.00
0.00
现在要求平均值,也就是把(123.23+26.35+58.42+23.00)/4,而零不做计算.请各位写出具体代码,别讲思路!!谢谢
e.Row.Cells[15].Text = ((double)(sum5 / GridView1.Rows.Count)).ToString("f");
e.Row.Cells[15].ForeColor = System.Drawing.Color.Red;
e.Row.Cells[16].Text = ((double)(sum6 / GridView1.Rows.Count)).ToString("f");
e.Row.Cells[16].ForeColor = System.Drawing.Color.Red;
上面的代码把0也算进去了.该怎么改?
