    }

    for (int i = 0; i < ListBoxAssignmentTechnology.Items.Count; i++)
    {
         sTechnologyvalue += ListBoxAssignmentTechnology.Items[i];

推荐答案

试试这个：

Try this:

string sTechnologyvalue = string.Empty;
string sToolsValue = string.Empty;
DataRow dr = dt.NewRow();

for (int i = 0; i < ListBoxAssignmentTools.Items.Count; i++)
{
     sToolsValue += ListBoxAssignmentTools.Items[i];
     sTechnologyvalue += ListBoxAssignmentTechnology.Items[i];
}

dr[0] = TextBoxFrom.Text;
dr[1] = TextBoxTo.Text;
dr[2] = TextBoxArea.Text;
dr[3] = TextBoxSector.Text;
dr[4] = TextBoxCompanyName.Text;
dr[5] = TextBoxDescription.Text;
dr[6] = sToolsValue;
dr[7] = sTechnologyvalue;

dt.Rows.Add(dr);

GridViewAllAssigments.DataSource = dt;
GridViewAllAssigments.DataBind();
Session["DataTable"] = dt;
