il

问题 Is it possible to view the IL code generated when you call Compile() on an Expression tree? Consider this very simple example: class Program { public int Value { get; set; } static void Main(string[] args) { var param = Expression.Parameter(typeof(Program)); var con = Expression.Constant(5); var prop = Expression.Property(param, typeof(Program).GetProperty(\"Value\")); var assign = Expression.Assign(prop, con); Action<Program> lambda = Expression.Lambda<Action<Program>>(assign, param).Compile

问题 I am curious to know why this is happening. Please read the code example below and the corresponding IL that was emitted in comments below each section: using System; class Program { static void Main() { Object o = new Object(); o.GetType(); // L_0001: newobj instance void [mscorlib]System.Object::.ctor() // L_0006: stloc.0 // L_0007: ldloc.0 // L_0008: callvirt instance class [mscorlib]System.Type [mscorlib]System.Object::GetType() new Object().GetType(); // L_000e: newobj instance void

问题 My question is relating to the performance characteristics of static methods vs instance methods and their scalability. Assume for this scenario that all class definitions are in a single assembly and that multiple discrete pointer types are required. Consider: public sealed class InstanceClass { public int DoOperation1(string input) { // Some operation. } public int DoOperation2(string input) { // Some operation. } // … more instance methods. } public static class StaticClass { public static
