How to create an exclude filter

NReflect

This page shows how to create an exclude filter.

Using an exclude filter

Suppose you want to reflect everything but private fields. Now you could use the include filter and specify everything which should be reflected. You will end up with a realy big block of code declaring the rules. To make things easier, you can use the include filter in conjunction with the invert filter as follows:

 1// Create the filter 
 2IncludeFilter includeFilter = new IncludeFilter();
 3includeFilter.Rules.Add(new FilterRule(FilterModifiers.Private, FilterElements.Field));
 4 
 5IFilter filter = new InvertFilter(includeFilter);
 6 
 7// Do the reflection 
 8NRAssembly nrAssembly;
 9try 
10{
11  Reflector reflector = new Reflector();
12  nrAssembly = reflector.Reflect("MyAssembly.dll", ref filter);
13}
14catch(Exception ex)
15{
16  Console.WriteLine("Exception while reflecting: " + ex.Message);
17  return;
18}
19 
20// Output the results 
21PrintVisitor printVisitor = new PrintVisitor();
22nrAssembly.Accept(printVisitor);

// Create the filter 
IncludeFilter includeFilter = new IncludeFilter();
includeFilter.Rules.Add(new FilterRule(FilterModifiers.Private, FilterElements.Field));
 
IFilter filter = new InvertFilter(includeFilter);
 
// Do the reflection 
NRAssembly nrAssembly;
try 
{
  Reflector reflector = new Reflector();
  nrAssembly = reflector.Reflect("MyAssembly.dll", ref filter);
}
catch(Exception ex)
{
  Console.WriteLine("Exception while reflecting: " + ex.Message);
  return;
}
 
// Output the results 
PrintVisitor printVisitor = new PrintVisitor();
nrAssembly.Accept(printVisitor);
