Hi Good evening All,

Can anyone tell me how to convert code from vb.net to c#.net.?
Is there any tool?

Can anyone tell me the c# code for the following code.

VB

       MultiView1.ActiveViewIndex = Int32.Parse(e.Item.Value)
       Dim i As Integer
       For i = 0 To Menu1.Items.Count - 1
           If i = e.Item.Value Then
               Menu1.Items(i).ImageUrl = "selectedtab.gif"
           Else
               Menu1.Items(i).ImageUrl = "unselectedtab.gif"
           End If
       Next
   End Sub

   Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
       If Page.IsPostBack = False Then

I converted the code from VB to C# like below..

VB Code:
MultiView1.ActiveViewIndex = Int32.Parse(e.Item.Value)
Dim i As Integer
'Make the selected menu item reflect the correct imageurl
For i = 0 To Menu1.Items.Count - 1
If i = e.Item.Value Then
Menu1.Items(i).ImageUrl = "selectedtab.gif"
Else
Menu1.Items(i).ImageUrl = "unselectedtab.gif"
End If
Next

C# code:

MultiView1.ActiveViewIndex = Int32.Parse(e.Item.Value);
for (int i = 0; i < Menu1.Items.Count-1;i++)
{
if(i=e.Item.Value)
{
Menu1.Items[i].ImageUrl = "selectedtab.gif";
}
else
{
Menu1.Items[i].ImageUrl = "unselectedtab.gif";
}
}

But still i am getting this error near "i=e.Item.Value"
CS0019: Operator '==' cannot be applied to operands of type 'int' and 'string'

Can anyone help me...

There is a web site that does code conversion for you: Developer Fusion: Convert VB.NET to C#[^]

This is the result from feeding it what you pasted into your question:

C#

protected void Menu1_MenuItemClick(object sender, MenuEventArgs e)
{
    MultiView1.ActiveViewIndex = Int32.Parse(e.Item.Value);
    int i = 0;
    for (i = 0; i <= Menu1.Items.Count - 1; i++) {
        if (i == e.Item.Value) {
            Menu1.Items[i].ImageUrl = "selectedtab.gif";
        } else {
            Menu1.Items(i).ImageUrl = "unselectedtab.gif";
        }
    }
}

protected void Page_Load(object sender, System.EventArgs e)
{
    if (Page.IsPostBack == false) {
        Menu1.Items(0).Selected = true;
    }
}

Some adjustments had to be made though. Like accessing the indexed property Items via [] and not with (). The Handles keyword is not present in C# so you'll have to hook up the event handlers via coding.

Cheers!

The code can be converted by with http://converter.telerik.com/[^] or using the link given in solution 1 by Manfred R. Bihy.

The converted code is as follows:

C#

protected void Menu1_MenuItemClick(object sender, MenuEventArgs e)
{
    MultiView1.ActiveViewIndex = Int32.Parse(e.Item.Value);
    for (int i = 0; i < Menu1.Items.Count; i++) {
        if (i == e.Item.Value) {
            Menu1.Items[i].ImageUrl = "selectedtab.gif";
        } else {
            Menu1.Items[i].ImageUrl = "unselectedtab.gif";
        }
    }
}

protected void Page_Load(object sender, System.EventArgs e)
{
    if (Page.IsPostBack == false) {
        Menu1.Items[0].Selected = true;
    }
}

After conversion the Menu1.Items(i) is converted as Menu1.Items(i) which may be the reason for an error, as the indexer property Items(i) is accessed using ( ) parentheses in VB.NET where as in C# the indexer property Items[i] is accessed using [ ].

Accordingly the above code is corrected. The C# does not allow Handles keyword, hence these methods have to be assigned to the corresponding events like

C#

Menu1.MenuItemClick += Menu1_MenuItemClick;

[Update]
The Solution is updated in response to the comment of OP below:

The error
Compiler Error Message: CS0019: Operator '==' cannot be applied to operands of type 'int' and 'string'
at the line
if (i == e.Item.Value)---------Here Error coming
is because of the reason that i is of int type and <code>e.Item.Value is string type which cannot be compared.

To resolve this error e.Item.Value can be converted to int
using Convert.Int32(e.Item.Value) and then it can be compared

As seen from the code, in the for loop ImageUrl property of the MenuItem which raised the click event is set to selectedtab.gif and for the other items it is set to unselectedtab.gif, which can be achieved by using the e.Item itself as follows without involving the overhead of conversion of e.Item.Value

C#

foreach (var item in Menu1.Items) {
    item.ImageUrl = e.Item == item ?
                "selectedtab.gif" : "unselectedtab.gif";
}

instead of the following for loop

C#

for (int i = 0; i < Menu1.Items.Count; i++) {
   if (i == e.Item.Value) {
       Menu1.Items[i].ImageUrl = "selectedtab.gif";
   } else {
       Menu1.Items[i].ImageUrl = "unselectedtab.gif";
   }
}

in the above code.
