问题

去掉特性即可，安装mono.cecil

using Mono.Cecil;
using System;

namespace DelSuppressIldasmAttribute
{
    internal class Program
    {
        static void Main(string[] args)
        {
            var input = "xxxx.dll";
            var output = "xxxx.dll";
            RemoveSuppressIldasmAttribute(input, output);
            Console.WriteLine("移除成功");
            Console.ReadKey();
        }

        public static void RemoveSuppressIldasmAttribute(string input, string output)
        {
            AssemblyDefinition assembly = AssemblyDefinition.ReadAssembly(input);
            foreach (CustomAttribute attribute in assembly.CustomAttributes)
            {
                if (attribute.Constructor.DeclaringType.Name == "SuppressIldasmAttribute")
                {
                    assembly.CustomAttributes.Remove(attribute);
                    break;
                }
            }

            assembly.Name.PublicKey = null;
            assembly.Name.PublicKeyToken = null;
            assembly.Write(output);
        }
    }
}
