推荐答案

您快到了，您需要类似以下内容:

You were nearly there, you need something like the following:

For Each row As DataGridViewRow In DataGridView1.Rows
    If Not row.IsNewRow Then
        MessageBox.Show(row.Cells(0).Value.ToString & "," & row.Cells(1).Value.ToString)
    End If
Next

如果您的 DataGridView 允许添加行，您需要检查 row.IsNewRow 是否不为 True.

You need to check if the row.IsNewRow is not True if your DataGridView allows adding rows.
