C# code problem

Hi !!!

I have translated a VB code to C# code but i have problem as it gives me an error that i can not solve.
my code is :-

this.treeView1.Nodes(refEmp.Type).Nodes(refEmp.SSN);

Type and SSN are read only properties that return only

: 'System.Windows.Forms.TreeView.Nodes' denotes a 'property' where a 'method' was expected

Please help what could be wrong!!!!

C# code problem

No, you can't have the same code in VB... it would generate an error...

The C# code:
this.treeView1.Nodes(refEmp.Type).Nodes(refEmp.SSN);

Would look like this in VB:
treeView1.Nodes(refEmp.Type).Nodes(refEmp.SSN)

But that line still doesn't do anything. It is incomplete. It would need to be something like:

treeView1.Nodes(refEmp.Type).Nodes(refEmp.SSN).Toggle()
or
treeView1.Nodes(refEmp.Type).Nodes(refEmp.SSN) = New TreeViewNode
or
myNode = treeView1.Nodes(refEmp.Type).Nodes(refEmp.SSN)

Otherwise the framework will generate the error "Property access must assign to the property or use its value."

You also need to be sure that the values returned by refEmp.Type and refEmp.SSN are integers that represent a valid index in the nodes collections.

As far as I can see, there is nothing wrong with the code that you have posted. Obviously there is a lot of code that you have not posted (other forms aswell as enums and structures), and the error lies somewhere there.

What type is refEmp.SSN
If it's a string type then it should work OK.

What value does refEmp.type have when the error occurs
If you only have 3 root nodes then it should always be either 0, 1 or 2.

We need more information than you're giving in order to help, but at the same time, we don't want to see your whole project.

Put a breakpoint on that line of code and find out what the values of refEmp.type and refEmp.SSN are when the error occurs.

I'm assuming that the () around the Nodes is a typo.

i just wander when i write the code like below igot the error
code:-

treeView1.Nodes(refEmp.type).Nodes.Add(refEmp.SSN);

Error:
 'System.Windows.Forms.TreeView.Nodes' denotes a 'property' where a 'method' was expected


please help ...i want to add a child node for a selected node ... this code is work fine in VB.NET but when translated t oC# got the error... please help

As previously pointed out, that cannot be the full code. There must be a line continuation in the VB code.

This code generates the error the error that you are recieving:
this.treeView1.Nodes[(int)0].Nodes[Convert.ToInt32(0)];

This code does not:
TreeNode myNode = this.treeView1.Nodes[(int)0].Nodes[Convert.ToInt32(0)];

In VB.net the error you would recieve is:
Property access must assign to the property or use its value.

Hi !!

Thanks for your reply.....

but i have the same code in VB.NET it works fine without errors and i just translate it to C# the property is read only (return) can you please help me more and give me hint as i am new user for the C#...i really apprecaite your help.
CConchelos
Thanks for your reply..... you are correct i got caught in the same problem where i need to change the brackets type

this is the new code

this.treeView1.Nodes[(int)refEmp.type].Nodes[Convert.ToInt32(refEmp.SSN)];

but the problem now it was complaining about the integert type should be in the bracket i treid to convert but got this error ... can you please help
The error is :-

Only assignment, call, increment, decrement, and new object expressions can be used as a statement

RKimble is correct, you can't have posted the entire line unless the line before it had a line continuation.

    Dim someValue As someThing = _
    treeView1.Nodes(refEmp.Type).Nodes(refEmp.SSN)

Is that a node array you're trying to access

VB:
    someValue = myArray(someItem)

C#:
    someValue = myArray[someItem];

() and [] tend to catch me out all the time.
Miyamoto M
The VB example:
TreeView1.Nodes(refEmp.Type).Nodes.Add(refEmp.SSN)

is calling the Add() method on the Nodes collection. That's why it is a complete statement. It looks like you're just missing the Add() method in your C# translation:

this.treeView1.Nodes[(int)refEmp.type].Nodes.Add([Convert.ToInt32(refEmp.SSN)]);

Now, I'm not sure about the ( ) around the value you want to add... have a C# person confirm the syntax...
markwebber&#35;1
That is an imcomplete line of code. You are accessing a property without using its value.

You need to either be calling a method on .Nodes(refEmp.SSN), setting it equal to something, or setting somthing equal to it.
Roygana
I thought you had this solved

I dont' think the code you just posted uses proper C# syntax... Doesn't the index of the Nodes collection have to be wrapped in square brackets [] instead of parentheses ()

treeView1.Nodes[refEmp.type].Nodes.Add(refEmp.SSN);

Hi !!

Thank you both for your help and being patient with me....it seems t obe solved now with the following code

treeView1.Nodes[Convert.ToInt32(refEmp.type)].Nodes.Add(refEmp.SSN);

But still i ma having problem ... i have in the treeview three nodes: Management, Union and Temp... in my form everytime you can add the new employee in the form and you should select the type of employee from the Drop down menu and once you click ok you got the employee listed beneath the type chosen.... now the proble m is when i add the first employee for the type: Temp or any other ... it is OK but when i add a second Employee to the same Type i give error signaling on the code above and seems to be it is not correct 100% can you please tell me how t osolve it i appreciate your help.

I don't think the () was a typo in the post. The error he is getting would indicate that he has parentheses after Nodes; that's why the compiler is expecting a method.
