C＃用逗号分割值 [英] C# split values by comma

问题描述

protected void btn_submit(object sender, EventArgs e)
    {
        string data = "";
        foreach (GridViewRow row in GrdRole.Rows)
        {
            if (row.RowType == DataControlRowType.DataRow)
            {
                CheckBox chkRow = (row.Cells[0].FindControl("chkCtrl") as CheckBox);
                if (chkRow.Checked)
                {
                    string EmployeeNo = row.Cells[2].Text;
                    data = data + EmployeeNo + ",";


                }
            }
        }
    }

任何想法如何分开这个？我的复选框输出= 30100001,30100002,30100004,30100005，

i wan将它逐个插入我的数据库



我尝试了什么：

any idea how to separate this?my checkbox output = 30100001,30100002,30100004,30100005,
i wan insert it one by one to my database

What I have tried:

string[] data1 = data.Split(',');
        for (int i = 0; i < data.Length; i++)
        {
            ClientScript.RegisterStartupScript(GetType(), "alert", "alert('" + data1 + "');", true);
        }

推荐答案

我在你的代码中看到一些问题：

I see a few problems in your code:

string[] data1 = data.Split(',');
for (int i = 0; i < data1.Length; i++)
{
    ClientScript.RegisterStartupScript(GetType(), "alert", "alert('" + data1[i] + "');", true);
}

见 更正 。



你为什么要用这么复杂的方式做事？

1）你有一个数据网格，持有 EmployeeNo

2）你在字符串中连接 EmployeeNo

3）如果 EmployeeNo

4）您启动数据库脚本，每个 EmployeeNo



您可以通过直接构建列表并跳过字符串步骤来合并2和3.

您可以通过不使用列表进一步简化并启动脚本，因为您知道 EmployeeNo ：

See corrections.

Why are you doing things in such a complicated way ?
1) you got a datagrid holding EmployeeNo
2) you concatenate the EmployeeNo in a string
3) you split the string in a list if EmployeeNo
4) you launch a database script with each EmployeeNo

You can merge 2 and 3 by building the list directly and skipping the string step.
you can simplify further by not using the list either and launch the script as you know the EmployeeNo:

if (chkRow.Checked)
{
    string EmployeeNo = row.Cells[2].Text;
    ClientScript.RegisterStartupScript(GetType(), "alert", "alert('" + EmployeeNo + "');", true);
}
