I am current trying to figure out how to read a mini dump file with code, I have an option to read the output of kd.exe and output in a form but i would rather try and figure out how to use the function MiniDumpReadDumpStream() contained within dbghelp.dll. I have search google to try and find something about it and c# but all i get is c++ examples and i honestly have no idea how to read c++. What is the best way to go about finding the info i need?

Ultimately, I just want to open and read a minidump file with as little effort as possible.

Hi,

Try using this from your c# app:

[DllImport("dbghelp.dll", SetLastError = true)]
public static extern bool MiniDumpReadDumpStream(IntPtr BaseOfDump,
   int StreamNumber,
   ref MINIDUMP_DIRECTORY Dir,
   ref IntPtr StreamPointer,
   ref UInt32 StreamSize);

Cheers, AT

I am pretty new to importing dlls, where would a good place to go for something like using that?

Really easy; the proper way to do it would be to make a seperate class with some static methods wrapping the imports but... I sugest that you just put this above the method that is going to use it, then you can call it normally.
You will need to add the using of System.Runtime.InteropServices

I am sorry, but i am super new to this, is there is an example I could see that would be of use? I googled more about interop and how to use the dllimport but I am not sure where to start

Hi,

I could make a rather elaborate example here but... two min of googling (is that a verb) and i found something you which might be close to what you are trying to accomplish. see http://www.java2s.com/Open-Source/CSharp/Plugin/walkmeil/Microsoft/Samples/Debugging/Native/DumpReader.cs.htm
