DataCollection.MarkProfile Method (Int32)

The MarkProfile method inserts a profile mark in the .vsp file. Profiling for the thread containing the MarkProfile function must be ON for the mark to be inserted.

Namespace:   Microsoft.VisualStudio.Profiler
Assembly:  Microsoft.VisualStudio.Profiler (in Microsoft.VisualStudio.Profiler.dll)

Syntax

public static MarkOperationResult MarkProfile(
    int markId
)

public:
static MarkOperationResult MarkProfile(
    int markId
)

static member MarkProfile : 
        markId:int -> MarkOperationResult

Public Shared Function MarkProfile (
    markId As Integer
) As MarkOperationResult

Parameters

• markId
  Type: System.Int32

  The marker to insert. The marker must be greater than or equal to 0 (zero).

Return Value

Type: Microsoft.VisualStudio.Profiler.MarkOperationResult

The return value, MarkOperationResult, is an enum.

Remarks

The mark value is inserted into the .vsp file each time the code runs if the thread containing the MarkProfile function is being profiled. You can call MarkProfile multiple times.

Profile marks are global in scope. For example, a profile mark inserted in one thread can be used to mark the start or end of a data segment in any thread in the .vsp file.

The profiling state for the thread that contains the mark profile function must be on when marks and comments inserted with the Mark command or with API functions (CommentMarkAtProfile, CommentMarkProfile, or MarkProfile).

Examples

The following example illustrates the MarkProfile method.

public void ExerciseMarkProfile()
{
    // Declare and initialize variables to pass to 
    // MarkProfile.  The values of these parameters 
    // are assigned based on the needs of the code;
    // and for the sake of simplicity in this example, 
    // the variables are assigned arbitrary values.
    int markId = 03;

    // Declare enumeration to hold return value of 
    // call to MarkProfile.
    MarkOperationResult markResult;

    markResult = DataCollection.MarkProfile(
        markId);

    Console.WriteLine("MarkProfile returned {0}", markResult);
}
