请问是否未支持使用泛型特性？

[YooRarely]

public class TryCatchAttribute : MoAttribute public class TryCatchAttribute<T> : MoAttribute

我设置了这样两条特性，TryCatchAttribute 可以正常使用 但是 TryCatchAttribute<T> 出错。 代码上他们长这样

    [TryCatch]
    public int Do(int t = 5)
    {
        throw new("");
    }
    [TryCatch<int>]
    public int Do2(int t = 5)
    {
        throw new("");
    }

Unhandled exception. System.TypeLoadException: Could not load type 'AOPUtil.TryCatchAttribute`1' from assembly 'Test, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.

我通过ILSPY查看源码 【正常版本 TryCatchAttribute 】

   [TryCatch]
    public int Do(int t = 5)
    {
        TryCatchAttribute tryCatchAttribute = new TryCatchAttribute();
        IMo[] mos = new IMo[1] { tryCatchAttribute };
        MethodContext methodContext = new MethodContext(this, typeof(Class2), MethodBase.GetMethodFromHandle((RuntimeMethodHandle)/*OpCode not supported: LdMemberToken*/, typeof(Class2).TypeHandle), isAsync: false, isIterator: false, mosNonEntryFIFO: false, mos, new object[1] { t });
        try
        {
            throw new Exception("");
        }
        catch (Exception exception)
        {
            methodContext.Exception = exception;
            tryCatchAttribute.OnException(methodContext);
            if (methodContext.ExceptionHandled)
            {
                return (int)methodContext.ReturnValue;
            }
            throw;
        }
    }

【错误版本 TryCatchAttribute<T>】

   [TryCatch<int>]
    public int Do2(int t = 5)
    {
        TryCatchAttribute<> tryCatchAttribute = (TryCatchAttribute<>)(object)new TryCatchAttribute<int>();
        IMo[] mos = new IMo[1] { tryCatchAttribute };
        MethodContext methodContext = new MethodContext(this, typeof(Class2), MethodBase.GetMethodFromHandle((RuntimeMethodHandle)/*OpCode not supported: LdMemberToken*/, typeof(Class2).TypeHandle), isAsync: false, isIterator: false, mosNonEntryFIFO: false, mos, new object[1] { t });
        try
        {
            throw new Exception("");
        }
        catch (Exception exception)
        {
            methodContext.Exception = exception;
            ((TryCatchAttribute<T>)(object)tryCatchAttribute).OnException(methodContext);
            if (methodContext.ExceptionHandled)
            {
                return (int)methodContext.ReturnValue;
            }
            throw;
        }
    }
