Question

I have a struct like this:

[StructLayout(LayoutKind.Sequential)]
internal struct EVENT_TRACE_PROPERTIES
{
    internal WNODE_HEADER WNode;

    [MarshalAs(UnmanagedType.ByValTStr, SizeConst = (int)EventTracePropertiesStringSize)]
    internal string LoggerName;

    [MarshalAs(UnmanagedType.ByValTStr, SizeConst = (int)EventTracePropertiesStringSize)]
    internal string LogFileName;
}

How can I copy a C# string, str to struct memory location pointed by LogFileName ?

Answer 1

You just assign to the field:

EVENT_TRACE_PROPERTIES item;
item.LogFileName = "My String";
