How to create a list with different type of data using vb.net?

问题

I need to create a list with different datatypes element, for example:

{{10, 10}, "IT", 1, "Test", {100, 100}, "Test"} 

respectively:

{object, string, integer, string, object, string}

I have tried declaring it as list of objects or using Tuple(Of Object, String, Integer, String, Object, String) but when I give them the values,

"Array initializer has too few dimensions"

error occurs.

The class where the variable is declared:

Public Class SignatureResponse

    Public signature As Tuple(Of Object, String, Integer, String, Object, String)

    Sub New()
        Me.signature = Nothing

    End Sub

    Sub New(ByVal signature As Tuple(Of Object, String, Integer, String, Object, String))
        Me.signature = signature
    End Sub
End Class

The class to which I use the parameter and assign the values:

Public Class Signature
      Inherits System.Web.Services.WebService

    <WebMethod()>
    <ScriptMethod(ResponseFormat:=ResponseFormat.Json, UseHttpGet:=False, XmlSerializeString:=False)>
    Public Function SendIdDocuments(ByVal idDocument As String, ByVal content As String, ByVal userId As String)
       Dim respDocs As New SignatureResponse
                respDocs.signature = {{10, 10}, "IT", 1, "Testing", {100, 100}, "Test Signature"}
             'Other part of development
            JSONString = JsonConvert.SerializeObject(respDocs)

        Return JSONString
    End Function

End Class

I am sending just the more important part of the code, they are more parameters used that works perfectly, except this one.

Error:

Any help please?

If you're using the old Tuple syntax as above then you can't create a new one in the way you've shown. You have to do:

    respDocs.signature =
        New Tuple(Of Object, String, Integer, String, Object, String)({10, 10}, "IT", 1, "Testing", {100, 100}, "Test Signature")
