clr

问题 I'm just going inside the CLR and IL and I'm confused by this thing. I have the following C# code: int x = 1; object obj = x; int y = (int)obj; And IL disassemble for this // Code size 18 (0x12) .maxstack 1 .locals init ([0] int32 x, [1] object obj, [2] int32 y) IL_0000: nop IL_0001: ldc.i4.1 IL_0002: stloc.0 IL_0003: ldloc.0 IL_0004: box [mscorlib]System.Int32 IL_0009: stloc.1 IL_000a: ldloc.1 IL_000b: unbox.any [mscorlib]System.Int32 IL_0010: stloc.2 IL_0011: ret So, the ldloc.0 instruction

问题 What determines which name is selected when calling ToString() on an enum value which has multiple corresponding names? Long explanation of question follows below. I have determined that this not determined uniquely by any of: alphabetical order; declaration order; nor, name length. For example, consider that I want to have an enum where the numeric values correspond directly to a practical use, (e.g. rgb values for color). public enum RgbColor { Black = 0x000000, Red = 0xff0000, Green =

问题 I've got a C# application which refers to a .NET DLL. If this DLL is present both in my application's bin directory and GAC, then which one will be picked up by the CLR at runtime? If GAC has the latest version, would that version be used instead of the one present in bin ? And how do I force the CLR to always use the one in my bin instead of GAC? According to MSDN: The CLR checks the global assembly cache, codebases specified in configuration files, and then checks the application's

问题 This question already has answers here : How CLR works when invoking a method of a struct (3 answers) Closed 6 years ago . What is the difference between two variable's ToString Calling ? int i = 0; i.ToString(); Does calling i.ToString() will make i first boxed then call ToString or i is already boxed before calling ToString() ? 回答1: int is an alias of System.Int32 struct type (implicitly sealed) which has a method Int32.ToString() and this is a method called in the second line of your code

问题 below is a code example from a book to show when a value type will be boxed: internal struct Point { private readonly Int32 m_x, m_y; public Point(Int32 x, Int32 y) { m_x = x; m_y = y; } //Override ToString method inherited from System.ValueType public override string ToString() { return String.Format("({0}, {1})", m_x.ToString(), m_y.ToString()); } } class Program { static void Main(string[] args) { Point p1 = new Point(10, 10); p1.ToString(); } } and the author says: In the call to ToString
