Exception handling 捕捉webmethod参数错误
我有一个这样的方法Exception handling 捕捉webmethod参数错误,exception-handling,webmethod,Exception Handling,Webmethod,我有一个这样的方法 [WebMethod] public static string UpdateProduct(Products obj) { DbTools.runcmd(TSQLCreate.Update(obj)); return "SUCCESS"; } public class Products : Books { public Products() {
[WebMethod]
public static string UpdateProduct(Products obj)
{
DbTools.runcmd(TSQLCreate.Update(obj));
return "SUCCESS";
}
public class Products : Books
{
public Products()
{
this.AddedDate = DateTime.Now;
///throw new NotImplementedException();
}
#region COMMON
[SQLIDColumn]
public int ProductID { get; set; }
[SQLColumn]
public string ProductName { get; set; }
[SQLColumn]
public string ProductCode { get; set; }
[SQLColumn]
public string Barcode { get; set; }
..............
private bool isOnePrice;
[SQLColumn]
public bool IsOnePrice
{
get { return isOnePrice; }
set { isOnePrice = value; }
}
private decimal onePrice;
[SQLColumn]
public decimal OnePrice
{
get
{
if (onePrice == 0M) onePrice = labelPrice;
return onePrice;
}
set {onePrice = value;}
}
}
并有一个用JS创建的XHR请求,用于将obj传递给wetmethod
SendOBJToMethod("some.aspx/UpdateProduct"
,obj // My Product Object
,function() { alert("Updated"); }); //SUCCESS FUNC
产品类别就是这样
[WebMethod]
public static string UpdateProduct(Products obj)
{
DbTools.runcmd(TSQLCreate.Update(obj));
return "SUCCESS";
}
public class Products : Books
{
public Products()
{
this.AddedDate = DateTime.Now;
///throw new NotImplementedException();
}
#region COMMON
[SQLIDColumn]
public int ProductID { get; set; }
[SQLColumn]
public string ProductName { get; set; }
[SQLColumn]
public string ProductCode { get; set; }
[SQLColumn]
public string Barcode { get; set; }
..............
private bool isOnePrice;
[SQLColumn]
public bool IsOnePrice
{
get { return isOnePrice; }
set { isOnePrice = value; }
}
private decimal onePrice;
[SQLColumn]
public decimal OnePrice
{
get
{
if (onePrice == 0M) onePrice = labelPrice;
return onePrice;
}
set {onePrice = value;}
}
}
问题:
当我以PropertyCIMAL OnePrice为空发送objectproduct时,我得到的错误值不是十进制的有效值
让我知道,是谁抛出的异常?
因为我想更改此消息
谢谢
