I need help converting some vb.net code to C#.net code

I need to change this to C# and I need to know where to put it.      

Public WithEvents UPED As New SIM.Charge
Is this the correct translation?
SIM.Charge UPED = new SIM.Charge();

When I run the code I get the error message below but the SIM.dll is in the path specified by the properties of the dll.


System.IO.FileNotFoundException was unhandled

To convert from VB.Net to C# just put a semi-colon at the end of every line! ;)


Your C# code to declare and instantiate the SIM.Charge object is correct. That error message would suggest your project is missing a reference - right click on your project, choose Add Reference, and add the DLL containing SIM.Charge to your project.

tgerbert!!

 Thanks for the response unfortunately neither suggestion worked.:(  Maybe I just don't know where to place them in the code.

Unfortunately, there is NO direct C# equivalent for the VB.Net WithEvents mechanism.

In VB.Net, you can subscribe to an event for a variable declared as "WithEvents" by tagging a sub with a "Handles" clause.

To convert that to C# you would need to manually "wire up" the event to your desired method.  This can be done either thru the IDE at design-time, or at run-time.

I was joking about the semi-colon thing, "SIM.Charge UPED = new SIM.Charge();" is correct. ;)

The error message reads Could not load file or assembly 'Hid.Net..., which means either Hid.Net couldn't be loaded, or some other DLL that Hid.Net itself uses couldn't be loaded. Do you have a Hid.Net.Dll? Did you add it as a reference to your project?

Subscribing to events won't do any good until we've got all the necessary assembly references. :P
Please post the complete code here So that I can help you out better.. :)

guys!!  Thanks for your posts!!!

Attached is the code that I am trying to run.  As you can see I have the SIM.dll in the using section and also have it in the references.

I am a very newbie in .Net.  

This is another line of code that needs to be translated:
UPED = New SIM.Charge(cboPort.Text, Baud, Parity, databits, cboDevice.SelectedIndex, txtLogLevel.Text)
 Where and how would declare UPED?

Thanks guys!!!

HI!

VB

Dim WithEvents MyButton As Button   ' WithEvents can't be used on local variable
MyButton = New Button

Private Sub MyButton_Click(ByVal sender As System.Object, _
  ByVal e As System.EventArgs) Handles MyButton.Click
  MessageBox.Show(Me, "Button was clicked", "Info", _
    MessageBoxButtons.OK, MessageBoxIcon.Information)
End Sub

C#

Button MyButton = new Button();
MyButton.Click += new System.EventHandler(MyButton_Click);

private void MyButton_Click(object sender, System.EventArgs e) {
  MessageBox.Show(this, "Button was clicked", "Info",
    MessageBoxButtons.OK, MessageBoxIcon.Information);
}
