从for循环到以逗号分隔的消息框的值 [英] Values from a for loop to a message box separated with comma

问题描述

我想把一个for循环的值用逗号分隔到一个消息框。

下面是我的for循环。

Hi,

I want to get the values from a for loop separated with comma in to a single message box.
Below is my for loop.

for (int i = 0; i < dtgrdUnconfirm.Rows.Count; i++)
                {
                    DataGridViewCheckBoxCell ch1 = new DataGridViewCheckBoxCell();
                    ch1 = (DataGridViewCheckBoxCell)dtgrdUnconfirm.Rows[i].Cells[0];
                    if (ch1.Value != null &&
                           Convert.ToBoolean(ch1.Value) == true)
                    {
                        data = (dtgrdUnconfirm.Rows[i].Cells[6].Value.ToString());
                    }
                }

在这个for循环中，字符串数据会得到4个值，我希望这4个值显示在用逗号分隔的单个消息框中。例如，输出应为1,2,3,4







先谢谢

In this for loop, string data will get 4 values and I want those 4 values to be shown in a single message box separated with comma. For example, output should be 1,2,3,4



Thanks in advance

推荐答案

我刚修改了你的代码

Hi,
I just modified your code

for (int i = 0; i < dtgrdUnconfirm.Rows.Count; i++)
                {
                    DataGridViewCheckBoxCell ch1 = new DataGridViewCheckBoxCell();
                    ch1 = (DataGridViewCheckBoxCell)dtgrdUnconfirm.Rows[i].Cells[0];
                    if (ch1.Value != null &&
                           Convert.ToBoolean(ch1.Value) == true)
                    {
                        data += (dtgrdUnconfirm.Rows[i].Cells[6].Value.ToString())+",";
                    }
                }
             MessageBox.Show(data);
