我从列表框中插入了数据。我想在 gridview 中检索特定技能集的数据。例如，如果我在下拉列表中选择 android 并按下按钮，它必须只给具有 android 技能的人。有人知道怎么做这个吗
private string GetConnectionString()
{
//Where DBConnection is the connetion string that was set up in the web config file
return System.Configuration.ConfigurationManager.ConnectionStrings["DBConnection"].ConnectionString;
}
private void InsertRecords(StringCollection sc)
{
SqlConnection conn = new SqlConnection(GetConnectionString());
StringBuilder sb = new StringBuilder(string.Empty);
foreach (string item in sc)
{
const string sqlStatement = "INSERT INTO Table1 (Employees) VALUES";
sb.AppendFormat("{0}('{1}'); ", sqlStatement, item);
}
try
{
conn.Open();
SqlCommand cmd = new SqlCommand(sb.ToString(), conn);
cmd.CommandType = CommandType.Text;
cmd.ExecuteNonQuery();
Page.ClientScript.RegisterClientScriptBlock(typeof(Page), "Script", "alert('Records Successfuly Saved!');", true);
}
catch (System.Data.SqlClient.SqlException ex)
{
string msg = "Insert Error:";
msg += ex.Message;
throw new Exception(msg);
}
finally
{
conn.Close();
}
}
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
StringCollection sc = new StringCollection();
foreach (ListItem item in ListBox1.Items)
{
if (item.Selected)
{
sc.Add(item.Text);
}
}
InsertRecords(sc);
}
