有没有办法装饰一些方法来做一些日志记录,然后无条件抛出异常呢？
我有这样的代码：
void foo(out int x)
{
if( condition() ) { x = bar(); return; }
// notice that x is not yet set here,but compiler doesn't complain
throw new Exception( "missed something." );
}
如果我尝试这样写,我会遇到一个问题：
void foo(out int x)
{
if( condition() ) { x = bar(); return; }
// compiler complains about x not being set yet
MyMethodThatAlwaysThrowsAnException( "missed something." );
}
有什么建议么？谢谢.
解决方法
这个怎么样？
bool condition() { return false; }
int bar() { return 999; }
void foo(out int x)
{
if (condition()) { x = bar(); return; }
// compiler complains about x not being set yet
throw MyMethodThatAlwaysThrowsAnException("missed something.");
}
Exception MyMethodThatAlwaysThrowsAnException(string message)
{
//this could also be a throw if you really want
// but if you throw here the stack trace will point here
return new Exception(message);
}
