背景

       在SWE当中，在对于XAML 文件进行解析的过程，经常会出现一个错误了，其以错误代码返回，错误代码其是一些数字。要想知道这些数字的含义，

       我们要去XamlRuntime.h 文件当中去查找，且查找过程麻烦。

       在一次看国外论坛的时候，看到了此类，感觉简单又方便使用。

 

示例：

  if (FAILED(retcode=app->CreateHostFromXaml(&xamlsrc, &wp, &vhost)))

{
            RETAILMSG( TRUE,

(L"%s\n",SWEErrorCode::GetSilverLightErrorString( retcode)));
           return retcode;
}

 

源代码

#pragma once

class SWEErrorCode
{
public:

static TCHAR*    GetSilverLightErrorString(
HRESULT retcode)
{
    static TCHAR    pszUnknownMessage[50];
    static    TCHAR    pszErrorStrings[][50] =
