Get all property name-value pairs from one class; pass to another...

[phobe62]

I have several classes that are going to dump their properties to a "mother ship" class. In trying to accomplish this, I'm using a foreach loop, like this:

------------------------------
public void MoveForward(System.Type t)
{
foreach (PropertyInfo propertyInfo in t.GetProperties())
{
// Set the property with this same name in another class to the value of the property in the class t
}
...
------------------------------

So... Does anybody know how it can be done?

I don't know the context in which you need to do:
>foreach (PropertyInfo propertyInfo in t.GetProperties())
{
// Set the property with this same name in another class to the value of the property in the class t
}

In the propertyInfo object you cannot change the NAME of the property.
Everything is readonly excepting the value of the property.
Example:
public MyClass {
private double _pTax=0.075;
public double TPS
{
get {return _pTax;}
set {_pTax = value;}
}
}
MyClass MyObj = new MyClass();
Type MyType = Type.GetType("MyObj");
PropertyInfo propertyInfo = MyType.GetProperty("TPS");
propertyInfo.SetValue( MyObj, 0.065, null);
The value of _pTax is now 0.065 but you cannot change its "TPS" accessor name.

Play" with the GetValue and SetValue methods. As long as the properties are not indexed and the types do not change between classes you should be OK.
Here is a "worst case" using fieldInfo, involving TypeChange

objTypecodeTo = System.Type.GetTypeCode(fldInfoTo(I).FieldType)
If Not (fldInfoFrom(I).GetValue(objFrom) Is Nothing) Then
Try
fldInfoTo(I).SetValue(objTo, _
System.Convert.ChangeType( _
fldInfoFrom(I).GetValue(objFrom), _
objTypecodeTo))
Catch ex As Exception
K += 1
strErrors(K) = strFldName & ": does not convert to Type=" & _
objTypecodeTo.ToString
End Try
End If
