推荐答案

您无法删除所选行。

尝试：

you can not delete selected rows.
try:

for (int AppiLib_Count = 0; AppiLib_Count < AppiLib.Count-1; AppiLib_Count++)
{
    //Validating the Selected Row in DataGridView
    if (dataGrid.SelectedRows.Count > 0)
    {
       //Deleting the Row on Macro Collapse
       dataGrid.Rows[dataGrid.SelectedRows[0].Index].Selected = false;
    
       dataGrid.Rows.Remove(dataGrid.Rows[dataGrid.SelectedRows[0].Index]);
    }
}
