Question

我有一个名为Mymethod的函数。它有三个参数。我想在Page_Load（）中调用它：我的问题是我应该用参数调用MyMethod函数。

public static string MyMethod(string Pro_id, string Sta_id, string Ity_id)
{
    try
    {
        MySqlConnection con = new MySqlConnection(Globals.CONNECTION_STRING);
        con.Open();
        String UserId = HttpContext.Current.Session["user_id"].ToString();

        MySqlCommand cmd = new MySqlCommand("INSERT INTO issue values ('" + UserId + "','" + Pro_id + "','" + Sta_id + "','" + Ity_id + "')", con);
        cmd.ExecuteNonQuery();
        con.Close();
    }
    catch (Exception err)
    {
        return "error";
    }
    return "success";
}

protected void Page_Load(object sender, EventArgs e)
{

}

你必须像这样调用你的方法：

 protected void Page_Load(object sender, EventArgs e)
 {
   string pro_id="xxx";//you need to assign it or retrieve somewhere
   string sta_id="xxx";//you need to assign it or retrieve somewhere
   string ity_id="xxx";//you need to assign it or retrieve somewhere

  MyMethod(pro_id, sta_id, ity_id);
 }

当您调用方法时，您不必编写参数类型。只需在cas string

中写下与参数类型相同的变量的名称

如何将函数调用到具有参数的主类？
