Is there a free tool capable of pruning unused code from a CLI assembly? I know there are obfuscators that are capable of performing this optimization, but these all cost money. Is there a free (or even open source) tool that removes the unused code in an already compiled assembly? Jb Evain There is. It's called the Mono.Linker . What I wrote three years about the Mono.Linker ago pretty much still

Suppose I have the following code: public class Class1 { private Class2 obj; public void MethodA() { var class2 = new Class2(); class2.PropertyI = 2; obj = MethodB(class2); } public Class2 MethodB(Class2 class2) { return class2; } } public class Class2 { public int PropertyI { get; set; } } The generated IL code from compiling with Visual Studio 2010 as a .NET 2.0 assembly is the following: .method public hidebysig instance void MethodA() cil managed { .maxstack 3 .locals init ( [0] class ClassLibrary1.Class2 class2) L_0000: nop L_0001: newobj instance void ClassLibrary1.Class2::.ctor() L_0006

I'm initializing an integer variable like this: LocalBuilder a = ilGen.DeclareLocal(typeof(Int32)); How can I access it and assign a value to it? I want to do something like this: int a, b; a = 5; b = 6; return a + b; Use the Ldloc and Stloc opcodes to read and write local variables: LocalBuilder a = ilGen.DeclareLocal(typeof(Int32)); LocalBuilder b = ilGen.DeclareLocal(typeof(Int32)); ilGen.Emit(OpCodes.Ldc_I4, 5); // Store "5" ... ilGen.Emit(OpCodes.Stloc, a); // ... in "a". ilGen.Emit(OpCodes.Ldc_I4, 6); // Store "6" ... ilGen.Emit(OpCodes.Stloc, b); // ... in "b". ilGen.Emit(OpCodes.Ldloc,

Why the C# 7 Compiler turns Local Functions into methods within the same class where their parent function is. While for Anonymous Methods (and Lambda Expressions) the compiler generates a nested class for each parent function, that will contain all of its Anonymous Methods as instance methods ? For example, C# code (Anonymous Method) : internal class AnonymousMethod_Example { public void MyFunc(string[] args) { var x = 5; Action act = delegate () { Console.WriteLine(x); }; act(); } } Will produce IL Code (Anonymous Method) similar to: .class private auto ansi beforefieldinit AnonymousMethod

I've written a program (in C#) that reads and manipulates MSIL programs that have been generated from C# programs. I had mistakenly assumed that the syntax rules for MSIL string constants are the same as for C#, but then I ran into the following situation: This C# statement string s = "Do you wish to send anyway?"; gets compiled into (among other MSIL statements) this IL_0128: ldstr "Do you wish to send anyway\?" I wasn't expecting the backslash that is used to escape the question mark. Now I can obviously take this backslash into account as part of my processing, but mostly out of curiosity I

Has any work been done on the direct conversion of CIL to LINQ expression trees? This would include class libraries, blogs, books, academic papers, etc. What are the known mismatches between CIL and LINQ Expression API? I have seen a project that significantly extended the Expression API to support an almost complete mapping between C# and LINQ Expressions. What work arounds would be suggested to accommodate any of these mismatches? Is there something fundamentally wrong about converting directly from CIL to LINQ Expressions? If so, why? 来源： https://stackoverflow.com/questions/12824201/how-to

I'm trying to write my own toy My Toy Language -> MSIL compiler in order to get a better understanding of how compilers work. I got the parsing and lexing working, I have built the expression trees and using the System.Linq.Expressions expression tree API, I have a working interpreter. Now I would like to emit some real MSIL assemblies. The problem is, I can't figure out how to actually build these assemblies. The MethodBuilder class only accepts raw MSIL method bodies, so I have to get the raw MSIL of my expression tree. Calling Expression.Compile() returns a working delegate but I'm not able
