我有两个datagridviews: 带有网格A和B(单元格[0],单元格1)的datagridView1:
datagridView2 (Cells[0], Cells[1], Cells[2]):
我想比较两个表之间的值,如果:
-the value in datagridView1.rows[i].Cells[0].value = datagridView2.rows[j].Cells[0].value AND the value in datagridView1.rows[i].Cells[1].value = datagridView2.rows[j].Cells[1].value THEN write in datagridView1.rows[i].Cells[2].value the value from the third column in datagridView2:

我相信您正在寻找类似的东西。这取决于您如何填充DataGridView
。也没有应该执行的错误处理。
for (var i = 0; i < dataGridView1.Rows.Count; i++)
{
var r1 = dataGridView1.Rows[i];
var r2 = dataGridView2.Rows[i];
if (r1.Cells[0].Value == r2.Cells[0] && r1.Cells[1].Value == r2.Cells[1])
r1.Cells[2].Value = r2.Cells[2].Value;
}

这是我添加的用于匹配任何行并可以正常运行的第二个循环:
for (var i = 0; i < src1.Rows.Count; i++)
{
var r1 = src1.Rows[i];
for (var j = 1; j < src2.Rows.Count; j++)
{
var r2 = src2.Rows[j];
if (r1[0].Equals(r2[0]) && r1[1].Equals(r2[1]))
{
r1[2] = r2[2];
}
}
}
