Programmatically access the CIL for a .NET type
- by Jordão
Is there a straighforward library that I can use to access the CIL for a .NET type? Let me demonstrate what I want the fictitious CilExtractor to do:
[Serializable]
public class Type_For_Extract_Cil_Test {
private int _field = 3;
public int Method(int value) {
checked {
return _field + value;
}
}
}
[Test]
public void Extract_Cil_For_Type_Test() {
string actualCil = CilExtractor.ExtractCil(typeof(Type_For_Extract_Cil_Test));
string expectedCil = @"
.class public auto ansi serializable beforefieldinit Type_For_Extract_Cil_Test
extends [mscorlib]System.Object
{
.method public hidebysig specialname rtspecialname instance void .ctor() cil managed
{
.maxstack 8
L_0000: ldarg.0
L_0001: ldc.i4.3
L_0002: stfld int32 Type_For_Extract_Cil_Test::_field
L_0007: ldarg.0
L_0008: call instance void [mscorlib]System.Object::.ctor()
L_000d: ret
}
.method public hidebysig instance int32 Method(int32 'value') cil managed
{
.maxstack 8
L_0000: ldarg.0
L_0001: ldfld int32 Type_For_Extract_Cil_Test::_field
L_0006: ldarg.1
L_0007: add.ovf
L_0008: ret
}
.field private int32 _field
}";
// indentations and code formatting issues apart, this should succeed
Assert.AreEqual(expectedCil, actualCil);
}
I know I can do this with Mono.Cecil or Reflector, but I also know I have to write a lot of code to achieve this. Since Reflector already does this on its UI, isn't there a simple way to access this functionality, like with a simple method call? Are there other libraries that are better suited to this specific scenario?
