Saving a variable as a reference in an object

[Christopher]

Hi all,

I am trying to store a reference to a variable in my data providerr class
but cannot save a reference to it. Can anyone help me?

I would like this code to allow me to store any field by referenece so that
it's contents can be written to using the Value property.

Code sample:
============
public class MyField
{
private string strFieldName;
private object objValue;

public string FieldName {set{strFieldName=value;}get{return(strFieldName);}}
public object Value {set{objValue=value;}get{return(objValue);}}

public SqlField(string pFieldName,
ref object pObject) /* THIS LINE DOES NOT WORK AT POINT REF */
{
strFieldName=pFieldName;
objValue=pObject;
}

Then in the program it is called using:
=======================================
int y=0;
MyField m = new MyField("id", ref y);
y=26;

Results wanted:
===============
m.Value is 0,
m.Value is 26 when y is set to 26

Please note that I don't always want to store an integer, it maybe a string
or other object.

Thanks in advance
Chris

In C# there is no support for references to value types other than in constructor or method parameters. This means you cannot define
a variable capable of holding a reference to other variable. Store a reference to a delegate or interface that has a method that
modifies the variable instead.
