ArrayList: Type casting error with ArrayList Objects
Dear All,
I created one ArrayList
ArrayList^ myAL = gcnew ArrayList;
myAL->Add('#');
myAL->Add("4");
myAL->Add(3);
myAL->Add(1.5);
Finally I want to assign each type of element to String type. But I am getting Type Casting Problem, I have applied many tricks , but most of them are failed
I need this
String ^one=myAL[0];
String ^two=myAL[1];
String ^three=myAL[2];
String ^four=myAL[3];
Obviously I must need explicit casting, I have applied explicit casting in many ways Like
String ^ one=myAL[0]->ToString()
But unfortunately , instead of “#”, “35” are copied into the string object.
For others I have also got surprising results.
I only need to convert all the contents converted into string object.
Please Suggest me how can I do this , better if you write a line of casting for me.
Thanks
Regards
Aijaz Soomro.

Re: ArrayList: Type casting error with ArrayList Objects
You should be using the generic list class instead of ArrayList for just about everything now : ArrayList has been included in .NET 2.0 for backwards compatibility with .NET 1.1.
e.g.
Code:
using namespace System::Collections::Generic;
List<System::String ^> ^list = gcnew List<System::String ^>;
list->Add(wchar_t('#').ToString());
list->Add("4");
list->Add(int(3).ToString());
list->Add(int(1.5).ToString());
Darwen.
