为此，您可以在属性中提供复选框列?转到属性并添加复选框列.完成.添加按钮并放置以下代码.

void select_btnClick(object sender, EventArgs e)
        {
            try {
                if(dataGridView1.SelectedRows.Count>0)
                {
                    foreach(DataGridViewRow row in dataGridView1.Rows)
                    {
                        DataGridViewCheckBoxCell  cbc = (DataGridViewCheckBoxCell ) row.Cells[0];
                        cbc.TrueValue=true;
                        bool myvalue=(bool)cbc.Value;
                        bool myvalue1=(bool)cbc.TrueValue;
                        if(myvalue==myvalue1)
                        {
                            int index=row.Index;//you will get the selected index here
                           //do the operation here
                        }
                    }
                }

for this you can provide checkbox column right??go to properties and add checkbox column..and you are done..add a button and place following code.

void select_btnClick(object sender, EventArgs e)
        {
            try {
                if(dataGridView1.SelectedRows.Count>0)
                {
                    foreach(DataGridViewRow row in dataGridView1.Rows)
                    {
                        DataGridViewCheckBoxCell  cbc = (DataGridViewCheckBoxCell ) row.Cells[0];
                        cbc.TrueValue=true;
                        bool myvalue=(bool)cbc.Value;
                        bool myvalue1=(bool)cbc.TrueValue;
                        if(myvalue==myvalue1)
                        {
                            int index=row.Index;//you will get the selected index here
                           //do the operation here
                        }
                    }
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }
