Passing a string to an unsafe struct.

Question

Hi Guys,

 

I need to interact with some old Delphi DLLs.

Unfortunately they use the Delphi shortstring variable.

Im having trouble accessing the DLL functions, Im trying to pass in a string parameter when the function requires a Delphi shortstring variable.

 

I found a reply online which suggested using a struct to create the shortstring variable in c#

I've pasted in the unsafe struct DelphiShortString struct to my code, but Im now having trouble passing the string to the struct. 

 

DelphiShortString variablename; 

 

How to I pass a string to variablename?

 

Thanks for your help.
