C＃用逗号分割值
问题说明
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);
}正确答案
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
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);
