C# Cecil:操作可能在运行时不稳定

我按照提示，甚至写了以下几行：

var MSILWorker = prop.SetMethod.Body.GetILProcessor();
MSILWorker.Body.InitLocals = true;

我在两个类中有两个属性：

 [NotifyProperty]
 public int Number { get; set; }

及

生成的IL代码完全相同，当然除了属性的名称和支持字段的类型。然而第一个抛出了VerificationException（“操作可能会破坏运行时的稳定性”），第二个则没有。 我可能做错了什么

编辑：以下是有问题的IL:

.method public hidebysig specialname instance void set_Number(int32 'value') cil managed
{
    .custom instance void [mscorlib]System.Runtime.CompilerServices.CompilerGeneratedAttribute::.ctor()
    .maxstack 3
    L_0000: nop 
    L_0001: ldarg.0 
    L_0002: ldarg.1 
    L_0003: stfld int32 TestApplication.SLTest.SLBOComposite::<Number>k__BackingField
    L_0008: ldarg.0 
    L_0009: ldstr "Number"
    L_000e: call instance void TestApplication.SLTest.SLBOComposite::RaisePropertyChanged(string)
    L_0013: nop 
    L_0014: ldarg.0 
    L_0015: ldstr "Number"
    L_001a: ldarg.1 
    L_001b: call instance void W3B.TestApplication.SLTest.SLBOComposite::Validate(string, object)
    L_0020: nop 
    L_0021: ret 
}

.method public hidebysing specialname实例void set\u Number（int32'值）cil托管
{
.custom instance void[mscorlib]System.Runtime.CompilerServices.CompilerGeneratedAttribute:：.ctor（）
.maxstack 3
L_0000：没有
L_0001:ldarg.0
L_0002:ldarg.1
L_0003:stfld int32 TestApplication.SLTest.SLBOComposite:：k_BackingField
L_0008:ldarg.0
L_0009:ldstr“编号”
L_000e:调用实例void TestApplication.SLTest.SLBOComposite:：RaisePropertyChanged（字符串）
L_0013：没有
L_0014:ldarg.0
L_0015:ldstr“编号”
L_001a:ldarg.1
L_001b:调用实例void W3B.TestApplication.SLTest.SLBOComposite:：Validate（字符串，对象）
L_0020:没有
L_0021:ret
}

没关系。：）

这就是解决办法

.method public hidebysig specialname instance void set_Number(int32 'value') cil managed
{
    .custom instance void [mscorlib]System.Runtime.CompilerServices.CompilerGeneratedAttribute::.ctor()
    .maxstack 3
    L_0000: nop 
    L_0001: ldarg.0 
    L_0002: ldarg.1 
    L_0003: stfld int32 TestApplication.SLTest.SLBOComposite::<Number>k__BackingField
    L_0008: ldarg.0 
    L_0009: ldstr "Number"
    L_000e: call instance void TestApplication.SLTest.SLBOComposite::RaisePropertyChanged(string)
    L_0013: nop 
    L_0014: ldarg.0 
    L_0015: ldstr "Number"
    L_001a: ldarg.1 
    L_001b: call instance void W3B.TestApplication.SLTest.SLBOComposite::Validate(string, object)
    L_0020: nop 
    L_0021: ret 
}

 L_001b: box int32
