如果只是问Grid合并代码，那么其实很简单：
//从grd的第rowIndex行colIndex列单元格以下count行合并
public static void 合并行(this GridView grd, int rowIndex, int colIndex, int count)
{
grd.Rows[rowIndex].Cells[colIndex].RowSpan = count;
for (var i = rowIndex + 1; i < rowIndex + count; i++)
grd.Rows[i].Cells[colIndex].Visible = false;
}
//从grd的第rowIndex行colIndex列单元格向右count列合并
public static void 合并列(this GridView grd, int rowIndex, int colIndex, int count)
{
grd.Rows[rowIndex].Cells[colIndex].ColumnSpan = count;
for (var i = 1; i < count; i++)
grd.Rows[rowIndex].Cells[colIndex + i].Visible = false;
}
然后你需要做的就是另外去考虑如何扫面数据的问题。例如一个for循环分别遍历每一行，看看之后有几行的值与当前行相同，如果返回的值>0则合并行并且对for循环变量加上这个数字（即跳过已经被合并的行）。这样一个思路就是你这个功能的架构设计。 --------------------编程问答-------------------- 然后你需要做的就是另外去考虑如何扫面数据的问题 --> 然后你需要做的就是另外去考虑循环Grid.Items的问题
