Accessor Problem!

Question

i got this routine from Bhagvan Chougule (Thanks) and i need to convert from VB to C#. I dont know how because i never saw before a accessor routine with parameters in C#.
The VB code:
Public Property Field(ByVal strFieldName As String, Optional ByVal rowNum As Integer = 0)
get
Return objDataTable(tableNum -1).Rows(rowNum) (strFieldName)
End Get
Set (ByVal Value)
objDataTable(tableNum -1).Rows(rowNum) (strFieldName) = Value
End Set
End Property
and i convert it to :
public string Field (string strFieldName, int rowNum)
{
get
{
return objDataTable(tableNum-1).Rows(rowNum)(strFieldName);
}
set
{
objDataTable(tableNum-1).Rows(rowNum)(strFieldName) = value;
}
}
but i have an error on the get and the set, asking for ";"
Help this newbie!

okay where do tableNum and objDataTable come from?
public string this[string strFieldName, int rowNum]
{
get
{
return objDataTable[tableNum].Rows[rowNum][strFieldName];
}
set
{
objDataTable[tableNum].Rows[rowNum][strFieldName] = value;
}
}
try this code, it's an indexer, that is the closest thing I have found to a property that can take parameters in C#.

thanks mike!
Let me explain the whole problem:
i have the user control routine drafted in vb. I dont know nothing about VB. (neither C# of course, but if i need a language i choose c#).
I want to make a project in c# and when i try to use the control (drafted in vb) i cannot do it. When i add the ascx file to my project, the project ask for a .cs file but i only have a vb file.
There is a way to use a ascx with vb into a c# project?
thanks in advance!

As far as I know, you can't pass parameters to properties in C#. What you'll need to do is probably have fields in your class such as CurrentRowNumber and CurrentFieldName. In this case, I would use a method. Below is the definition of a property from MSDN.

Here is the definition from MSDN:
Properties are an extension of fields and are accessed using the same syntax. Unlike fields, properties do not designate storage locations. Instead, properties have accessors that read, write, or compute their values.
Property declaration takes one of the following forms:
[attributes] [modifiers] type identifier {accessor-declaration}
[attributes] [modifiers] type interface-type.identifier {accessor-declaration}
where:
attributes (Optional)
Additional declarative information. For more information on attributes and attribute classes, see C# Attributes.
modifiers (Optional)
The allowed modifiers are new, static, virtual, abstract, override, and a valid combination of the four access modifiers.
type
The property type, which must be at least as accessible as the property itself. For more information on accessibility levels, see Access Modifiers.
identifier
The property name. For more information on interface member implementation, see interface.
accessor-declaration
Declaration of the property accessors, which are used to read and write the property.
interface-type
The interface in a fully qualified property name. See Interface Properties.
