问题
I want to temporarily disable a breakpoint for a short time, so I set a conditional breakpoint with the following condition:
(global::System.DateTime.Now<new global::System.DateTime(2014,03,28,11,0,0))
When this breakpoint is hit a dialog pops up, saying
The condition for a breakpoint failed to execute. The condition was
'(global::System.DateTime.Now<new
global::System.DateTime(2014,03,28,11,0,0))'. The error returned was
'The runtime has refused to evaluate the expression at this time.'. Click
OK to stop at this breakpoint.
Why has the runtime refused to evaluate the expression?
What can I do to get the desired behavior without modifying the debugged source code?
回答1:
From VS2012 on, you have to switch to the Managed Compatibility Mode, to use conditional breakpoints. Why and how is described here:

It's not possible as far as I know. What you can do instead is use of HitCount
or hardcode with a timer (as you like) in C#
code
#if DEBUG
if(System.Diagnostics.Debugger.IsAttached)
System.Diagnostics.Debugger.Break();
#endif
