Question

在ASP.NET网络表格中,i 很容易做到:

[...]
try
{
    DateTime date = Convert.ToDateTime("abc");
}
catch(Exception ex)
{
   lblErrorMessage.Text = ex.Message;
}

Now the question is:How can i do the same in ASP.NET MVC? Ive been looking for it and all i found is [HandleError] attribute.I dont want to redirect user to a "Error.aspx" View if an exception occurs.I want to show error messages in the same page like in Web Forms.

Answer 1

try
{
    DateTime date = Convert.ToDateTime("abc");
}
catch(Exception ex)
{
   ViewData["Error"] = ex.Message;
}
return View();

在您看来或主页上,检查是否定了“Error”一词。如果是的话,就显示你的错误。

<% if (ViewData["Error"] != null)
{
    <div class="error"><%=html.encode(ViewData["Error"]) %></div>
}
%>

Answer 2

try 
{ 
    DateTime date = Convert.ToDateTime("abc"); 
} 
catch(Exception ex) 
{ 
   ModelState.AddModelError("date", ex)
}

当时认为

<%= Html.ValidationSummary() %>

Answer 3

• 建立你自己的特性,执行IExceptionFilter 。你也可以回头来,在观点中树立了价值,但一个属性将给你更标准的处理方式。
