GetVariantArrayValueMBS(v as Variant, index as Integer) as Variant

Type Topic Plugin Version macOS Windows Linux iOS Targets
global method XojoRuntime MBS Util Plugin 13.0 ✅ Yes ✅ Yes ✅ Yes ✅ Yes All
Queries a variant from an array inside a variant.
Example 
// some part of app builds an array
Var a() as pair
a.Append 1:"Hello"
a.Append 2:"World"

// passes it as Variant somewhere else

Var v as Variant = a

// and later you may want to get values back without knowing the array type

// this raises TypeMismatchException
'dim o() as Object = v

// so use plugin to get objects:
Var v1 as Variant = GetVariantArrayValueMBS(v, 0)
Var v2 as Variant = GetVariantArrayValueMBS(v, 1)

// now you can check type and cast to the object type
Var p1 as pair = v1
Var p2 as pair = v2

MsgBox p1.Right+" "+p2.Right

This function is to allow getting objects from an array inside a variant without known the class used to declare array.
Returns nil on any error.

Updated in 13.5 plugins to raise exception is array is nil.

Also updated in v13.5 to work with object, variant, string, date, integer, double, single, boolean, Int64 arrays. Other array types will raise exception.
