警告不在asp.net中显示异常变量

Question

我想在asp.net 4的警告框中显示异常.但它没有显示任何警报.我试过这些解决方案 -

try{// my code}
catch (Exception ex)
            {             
                //Response.Write("<script>alert('" + Server.HtmlEncode(ex.Message) + "')</script>"); // Not Working
                //Response.Write("<script>alert('" + ex.Message + "');</script>"); // Not working
       // Response.Write("<script>alert('" + Server.HtmlEncode(ex.ToString()) + "')</script>"); // Not working
//ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "done", "alert('Error Occured.');", true); // Only this is working.
            }

如果我出错,请建议任何解决方案.

谢谢和问候,Rizwan Gazi.

Answer 1

通常Response.Write();总是有效.但正如你所说它不起作用

试试这个 :

ScriptManager.RegisterClientScriptBlock(this, typeof(Page), "done", "alert('" + ex.Message.Replace("'", "") + "');", true);

如果它能解决您的问题,请告诉我.
