Solutions or workaound for Visual Studio conditional breakpoint slowness

Question

I'm using a conditional breakpoint to determine when a C# DateTime variable is greater than a certain time. This breakpoint will be checked approximately 50,000 times in a run.

my conditional breakpoint looks like:

quote.Time > new DateTime(2014,2,4,3,59,0)

Without this conditional break point my test run takes about 15 seconds. With the conditional breakpoint it takes 45 minutes.

Is there anything I can do to help speed this without modifying the code I'm debugging to add an assert or conditional?

Is there anyway to make it calculate the DateTime variable only once? Or is this more of an architectural issue with how conditional breakpoints are implemented in the IDE?

Answer 1

why don't you stop using a conditional break point and change the code until you have debugged it. so the code would become something like:

int dummyx = 0;
if (quote.Time > new DateTime (2014,2,4,3,59,0 )
{

dummyx++; // put normal break point here!

}

This will run much faster.

Answer 2

Just for debugging purposes I'd say create a new if-statement and a dummy variable (like int i = 0;) and set the breakpoint on that line. Then just step into / step through the rest of the code.. Just for testing, you can always just remove those 1-2 lines of code after testing.

The if-statement (logically) containing: if (quote.Time > new DateTime(2014,2,4,3,59,0)) { int i=0; }
