MapInfo Pro Developers User Group

Hello, 

I have already asked this question on MapInfo-L group, but I didn't get right answer. 

Basically, I'm trying to pass array of strings to MBX Sub from C# assembly. 

C# part of code:

string[] subParams = { "param1", "param2"}
mbxApp.CallMapBasicSubroutine("MySub", subParams); ​

MabBasic sub:

Declare Sub MySub(subParams() as String)

Sub MySub(subParams() as String)  

  Print "Sub launched"

End Sub

Interestingly,  nothing happens when I run this code, you'll notice I haven't used any array member in Sub, just tried to print out message. No exception is caught both on C# and MB side. 

Until now I have been passing single string (concatenated array members, delimited by semicolon), and then I would split them in Sub, however it would be nice to do it right way.

Hi Marijan,
We don't support passing array from C# to MapBasic sub. Passing single string (concatenated array members, delimited by semicolon), and then I would split them in Sub is the only way right now.

Anshul, 

I was confused by method signature. Both in VS and ExtensibilityReferenceHelp is offered as string array. 

Thank you for your answer

Hi Marijan,
Second parameter in CallMapBasicSubroutine is an array which notifies the number of parameter to the mapbasic sub.
