How to use a partial class?
-
Hi, I am trying to split a class(Class1) to different files, hence i have changed the access specifier for the Class1 to Partial. I have created one more class with the same name(Class1) and same namespace. From the second class file which i created, i am able to access the procedures / functions from the first class file, but i am not able to access the variables which are used there. Can anyone help me to access the variables from the first class file. Regards N.Surendra Prasad

That's just not possible. If you have a partial class, properly declared, then the variables and methods are all together in the one class. Having said that, when I do a partial class, I tend to make it so that variables are used in methods in the same file. That just makes sense of the whole concept

I have the variables and methods inside one class. I want to break that class into two classes so that the size of the class is reduced. That is the reason why i went for partial class concept. I have few variables which will be used throughout the class, so they have been declared globally in that class. When i tried moving few methods to the other class file, i am not able to access those global variables which are there in the first class file. Can you help me on this? Regards N.Surendra Prasad

I don't know what this means, how is something declared globally, but within a class ? Do you mean a member variable ?

You need to post some code, so we can see what's going on.

Hi Christian, Here is the code which i have used. File1: Partial Class TEWebClass Inherits UI.Page Protected cnn As New ADODB.Connection Protected rs As ADODB.Recordset Protected rs2 As ADODB.Recordse End Class File2: Partial Class TEWebClass Inherits UI.Page Public Sub clientadd_ProcessForm() Dim formError As Boolean Dim itemOK As Boolean Dim errortext As String ... End Sub End Class These are two different files with the same class name. From File2, i need to access the variable cnn which is declared in File1. I tried, but not able to do it. Can you help me.

I presume you need to keep variables in one file and methods in other, right ? So your partial class would be like file name would be
MyClass.Variablespartial class MyClass
{
public int a;
private string b;
//etc
}file name would be
MyClass.Methodspartial class MyClass
{
//Methods goes here
}when compiled, this will act as a single class. You can access variables as you do in normal class.

Your code looks OK. Are you getting any error ?

Hi Navaneeth, I tried using the cnn variable from File2, it throws the error "variable cnn not declared" N.Surendra Prasad Winning doesn't always mean being first, winning means you're doing better than you've done before.

If you have any namespace defined, make sure it is same for both files.
