ASP.NET C# Multiple possible return types

[neaox]

Hey Everyone,

I'm wanting to create a fuction that has 2 or more possible return types if thats possible. I.E

public String, Boolean testfunction(string input, string returntype="boolean"){
if(input == "String" && returntype=="boolean")
return true;
else
return false;

if(input == "String" && returntype=="string")
return "string is equal to string";
else
return "string is not equal to string";
} 

Thanks for any help you can give

This is by far not the best way but it would work...

Create three functions that will do the checks for you. I hope this helps

Public Overridable Function CheckThis(ByVal input As Object) As Object
        Dim something As Object = Nothing
        If isBool(input) = True Then
            something = True
        ElseIf isString(input) = "yes" Then
            something = "Is String"
        End If
        Return something
    End Function

    Public Overridable Function isBool(ByVal input As Object) As Object
        If TypeOf input Is Boolean Then
            Return True
        Else
            Return False
        End If
    End Function

    Public Overridable Function isString(ByVal input As Object) As Object
        If TypeOf input Is String Then
            Return "yes"
        Else
            Return "not string"
        End If
    End Function

Hi Matt,

Thanks for that what i'm aiming to do is create a easy SQL database class this class includes a query function this function splits the query string by ';' and exetues each query if the query is a "SELECT" query it will return a dataset, if it is a "INSERT INTO", "UPDATE", "DELETE" it will return an int of the number of rows inserted, updated or deleted. So this function will return only one object but it could one of two possible datatypes.. is it possible to have a function with 2 possible return datatypes?

My prefered ASP.NET coding language is C# so any help in this lanugage would be better.

Thanks,

Chris
