如何比较dataGridView中的2行并突出显示不同的单元格？

如何比较dataGridView中的两个选定行？ 1.-我需要知道如何检测两个选定的行2.-比较两个选定的行3.-突出显示差异“单元格”

我试过这个但不幸的是我迷路了……

DataTable src1 = dataGridView1.DataSource as DataTable; //THIS IS PROBABLY NOT NEEDED DataTable src2 = dataGridView1.DataSource as DataTable; int index1 = 0; for (int i = 0; i < src1.Rows.Count; i++) { var row1 = src1.Rows[i].ItemArray; var row2 = src2.Rows[i].ItemArray; for (int j = 0; j < row1.Length; j++) { if (!row1[j].ToString().Equals(row2[j].ToString())) { dataGridView1.Rows[i].Cells[j].Style.BackColor = Color.Red; dataGridView1.Rows[i].Cells[j].Style.BackColor = Color.Red; } } }

实际上你的代码不好我会回答你的问题：

1.-我需要知道如何检测两个选定的行

 dataGridView1.SelectedRows 

2.-比较两个选定的行，它应该看起来类似于以下内容：

 for (int i = 0; i < dataGridView1.SelectedRows.Count-1; i++) { for (int j = 0; j < dataGridView1.SelectedRows.rows[i].Cells.Count; j++) { if(dataGridView1.SelectedRows.rows[i].Cells[j].value.Equals(dataGridView1.SelectedRows.rows[i+1].Cells[j].value)) { dataGridView1.SelectedRows.Rows[i].Cells[j].Style.BackColor = Color.Red; dataGridView1.SelectedRows.Rows[i+1].Cells[j].Style.BackColor = Color.Red; } } } 

3.-突出差异“细胞”

  dataGridView1.SelectedRows.Rows[i].Cells[j].Style.BackColor = Color.Red; dataGridView1.SelectedRows.Rows[i+1].Cells[j].Style.BackColor = Color.Red;
