Converting vb.net to c# with Object

Question

I have the following vb.net line:

Dim applesAs Object() = New Object([end] - startIndex - 1) {}

and Developer Fusion's Converter converts it to this c# line:

object[] apples= new object[end - startIndex - 1];

The c# code seems to create an array of objects called apples, however I cannot find what the constructor for Object in vb is doing. Is it also creating an array? Am I wrong about what the c# line seems to be doing?

It's just predetermining the size of the object array. It's not a constructor it is an array initializer. — EkoostikMartin

Your vb code looks as if it was translated from C# earlier ... (because that syntax is very unfamiliar for vb) — igrimpe

In C#, you use the size of the array, while in VB you use the upper bound, so the conversion should be: object[] apples = new object[end - startIndex]; — Dave Doknjas

@DaveDoknjas: Everything after and including the "=". Why wouldnt a VB guy simply write: Dim apples(maxindex) As Object ? — igrimpe

however I cannot find what the constructor for Object in vb is doing.

Its not a constructor call,() are used in VB.Net for array indexing.

Also there is no constructor accepting a parameter with Object

Both the vb.net and c# code are creating an object array called apples.

c# uses [] to indicate an array
vb.net uses () to indicate an array

The parameters set the size of the array

new Object(5) 'vb.net
new object[6] //c#

In C#, that would be "new object[6]" since the VB code specifies the upper bound, not the size.

@DaveDoknjas Thanks for that bit of info. I was not aware of that! I am new to vb.net.
