ProfileOptimization.SetProfileRoot Method

.NET Framework 4.5

Enables optimization profiling for the current application domain, and sets the folder where the optimization profile files are stored. On a single-core computer, the method is ignored.

Namespace:  System.Runtime
Assembly:  mscorlib (in mscorlib.dll)

public static void SetProfileRoot(
	string directoryPath


Type: System.String

The full path to the folder where profile files are stored for the current application domain.

You must call this method before you call the StartProfile method for the first time in the current application domain. If you call SetProfileRoot more than once in the same application domain, all calls after the first are ignored.

The specified folder must already exist. If it does not exist, calling this method does not create it, and no profiling occurs.

On computers that do not have multiple cores, this method is ignored.
