EventSource.EventData Structure

.NET Framework 4.5

Provides the event data for creating fast WriteEvent overloads by using the WriteEventCore method.

Namespace:  System.Diagnostics.Tracing
Assembly:  mscorlib (in mscorlib.dll)

protected internal struct EventData

The EventSource.EventData type exposes the following members.

Public propertySupported in .NET for Windows Store appsDataPointerGets or sets the pointer to the data for the new WriteEvent overload.
Public propertySupported in .NET for Windows Store appsSizeGets or sets the number of payload items in the new WriteEvent overload.

Public methodSupported in .NET for Windows Store appsEqualsIndicates whether this instance and a specified object are equal. (Inherited from ValueType.)
Public methodSupported in .NET for Windows Store appsGetHashCodeReturns the hash code for this instance. (Inherited from ValueType.)
Public methodSupported in .NET for Windows Store appsGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodSupported in .NET for Windows Store appsToStringReturns the fully qualified type name of this instance. (Inherited from ValueType.)

The following example shows how to use the EventSource.EventData structure.

        public unsafe void WriteEvent(int eventId, int arg1, int arg2, int arg3, int arg4) {
            EventData* dataDesc = stackalloc EventProvider.EventData[4];

            dataDesc[0].DataPointer = (IntPtr)(&arg1);
            dataDesc[0].Size = 4;
            dataDesc[1].DataPointer = (IntPtr)(&arg2);
            dataDesc[1].Size = 4;
            dataDesc[2].DataPointer = (IntPtr)(&arg3);
            dataDesc[2].Size = 4;
            dataDesc[3].DataPointer = (IntPtr)(&arg4);
            dataDesc[3].Size = 4;

            WriteEventCore(eventId, 4, (IntPtr)dataDesc);
