如何检查dataGridView复选框是否已选中? [英] How to check if dataGridView checkBox is checked?

问题描述

我是编程和C#语言的新手.我被卡住了，请帮忙.所以我已经编写了这段代码(c#Visual Studio 2012):

I'm new to programming and C# language. I got stuck, please help. So I have written this code (c# Visual Studio 2012):

private void button2_Click(object sender, EventArgs e)
{
    foreach (DataGridViewRow row in dataGridView1.Rows)
    {
         if (row.Cells[1].Value == true)
         {
              // what I want to do
         }
    }
}

所以我收到以下错误:

运算符'=='不能应用于类型为'object'和'bool'的操作数.

推荐答案

您应使用 Convert.ToBoolean()来检查dataGridView复选框是否已选中.

You should use Convert.ToBoolean() to check if dataGridView checkBox is checked.

private void button2_Click(object sender, EventArgs e)
{
    foreach (DataGridViewRow row in dataGridView1.Rows)
    {
         if (Convert.ToBoolean(row.Cells[1].Value))
         {
              // what you want to do
         }
    }
}
