c# - 您将如何发出类型的默认值？

Question

我想实现一个自动清除所有本地字段的接口(interface)，目前我有:

// Implement IClearable
dynamicType.AddInterfaceImplementation(typeof(IClearable));

MethodBuilder clearnMethodBuilder = dynamicType.DefineMethod("Clear", MethodAttributes.Public | MethodAttributes.Virtual, CallingConventions.Standard);
ILGenerator clearMethodILGen = clearnMethodBuilder.GetILGenerator();

foreach (FieldBuilder localField in fields)
{
    clearMethodILGen.Emit(OpCodes.Ldarg_0);
    clearMethodILGen.Emit(OpCodes.Ldfld, localField);
    clearMethodILGen.Emit(OpCodes.??, Profit??);
}

clearMethodILGen.Emit(OpCodes.Ret);

如何设置最后一步以保存字段的默认值？

Answer 1

类似于:

clearMethodILGen.Emit(OpCodes.Ldfld, localField);
clearMethodILGen.Emit(OpCodes.Initobj, localField.FieldType);
