Class method doesn't seem to work

[tshad]

I have a class:
*******************************************
public class DecimalType
{
private decimal first = 0; //original data
private decimal data = 0; //current data
public bool nullFirst = false; //original Data null
public bool nullData = false; //current data null

public DecimalType()
{
}

public DecimalType(decimal initial)
{
first = initial;
data = initial;
}

public bool IsNull()
{
return nullData;
}

public bool IsFirstNull()
{
return nullFirst;
}

public void SetNull()
{
nullData = true;
data = 0;
}

public void SetFirstNull()
{
nullFirst = true;
first = 0;
}

// Properties

public decimal First
{
get { return first; }
set { first = value; }
}

public decimal Data
{
get { return data; }
set { data = value; nullData = false; }
}
} // end Class

********************************************

In another program I call the SetNull() method, but it isn't setting my
flag. If I directly set it, it works fine:

public static void GetValueFromDbObject(object dbObjectValue, ref
DecimalType destination)
....
destination.SetNull();
destination.Data = 2000;
destination.nullData = true;
....

If I comment out the direct change (destination.nullData), nullData is still
false. But above it is setting it to true. If I leave the
destination.nullData = true line in, the flag gets set.

Why doesn't the SetNull() method work?

Thanks,

Because your Data property is setting it to false.

Because your Data property is setting it to false.

Hence the reason for not putting multiple statements on one line.

I was looking at this over and over and assumed I was somehow setting it
back to false, but couldn't find it.

I actually want it to work that way, but I had put a test in just to see at
what point of the code I was for different types of tests and had forgotten
that when I set the propert to some value, I obviously want the Null to be
false as it isn't null anymore. The "destination.Data = 2000" was setting
to false, as you said.

Thanks,
