我想把Gridview某一列里最小的十個(gè)數(shù)值變色，我的代碼如下，但老提示錯(cuò)誤，找不出什么錯(cuò)誤?；蛘哂懈玫膶懛?？protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)  {  double[] a = new double[GridView1.Rows.Count]; \\定義一個(gè)數(shù)組  for (int i = 0; i <= GridView1.Rows.Count -1; i++)  {  a[i] =Convert.ToDouble(GridView1.Rows[i].Cells[4].Text); \\把GridView1的某列的值賦值到這個(gè)數(shù)組  }  Array.Sort(a); \\排序  for (int k = 0; k < 10; k++)     {  double b = a[k]; \\讀出排在前10位的數(shù)  for (int i = 0; i <= GridView1.Rows.Count - 1; i++)  {  double c = Convert.ToDouble(GridView1.Rows[i].Cells[4].Text); \\查找每行的值  if (b == c) \\如果等于這個(gè)數(shù)的  {  GridView1.Rows[i].Cells[4].BackColor = System.Drawing.Color.Yellow;\\那一行變色。  }  }  }  ｝
