使用时字典如何获取不可为空值类型的值

Question

何时使用字典

如果非空值键入此代码，我如何获取该值

            Dictionary<string, object> DictionaryValues = new Dictionary<string, object>();
            RSAParameters publicKey = Storage.Read(_Path + @"\" + "Key.Public");
            DictionaryValues["publicKey"] = publicKey;


            RSAParameters publicKey2 = new RSAParameters();
            if (DictionaryValues.TryGetValue("publicKey", out object obj))
            {
                publicKey2 = obj as RSAParameters;
                
            }

我收到一个错误 as 运算符必须与引用类型或可为空类型一起使用 RSAParameters is anon nullable

我如何从字典中获取值 publicKey 请帮忙，谢谢大家

Answer 1

//publicKey2 = obj as RSAParameters;
  publicKey2 = (RSAParameters)obj;
