如何在 datagridview 列中显示总和? [英] how I can show the sum of in a datagridview column?

问题描述

我需要显示此 datagridview 中 count 列的总和，但我不知道如何获取 datagridview 中的数据.

当我点击按钮时，我想在label1中显示94.

如何做到这一点?

解决方案

int sum = 0;for (int i = 0; i < dataGridView1.Rows.Count; ++i){sum += Convert.ToInt32(dataGridView1.Rows[i].Cells[1].Value);}label1.Text = sum.ToString();

I need to show the sum of the count column from this datagridview, but I don't know how I can get to the data in the datagridview.

When I click on the button, I want to show 94 in label1.

How can this be done?

解决方案

int sum = 0;
for (int i = 0; i < dataGridView1.Rows.Count; ++i)
{
    sum += Convert.ToInt32(dataGridView1.Rows[i].Cells[1].Value);
}
label1.Text = sum.ToString();
