How do I get the line number and path of a method from a pdb using .Net?

• Given an assembly and its pdb, how do I get the line number and path to a method using .Net?

• Answer:

  You will need to use the http://msdn.microsoft.com/en-us/library/t6tay6cz.aspx. Microsoft does not have a managed interface for it, but http://stackoverflow.com/questions/697541/how-do-i-use-the-ms-dia-sdk-from-c has been asked on StackOverflow before. If you are going to try it out in native first you can get the information in question by getting the IDiaSymbol instance for the PDB in question, this is called the http://msdn.microsoft.com/en-us/library/fkcc8hx6.aspx. Once you have that you will call http://msdn.microsoft.com/en-us/library/yfx1573w.aspx passing it the SymTagFunction enumeration which of type http://msdn.microsoft.com/en-us/library/bkedss5f.aspx. You will then need to enumerate over them and use an IDiaSession, previously made to get the global IDiaSymbol, instance to find the correct source and line number.
