Question

我开始使用可选参数（因为我来自java并且以前没有尝试过它们）而且我遇到了以下问题：

Unhandled Exception: Mono.CSharp.InternalErrorException: Internal error

  at Mono.CSharp.MethodGroupExpr.IsApplicable (Mono.CSharp.ResolveContext ec, Mono.CSharp.Arguments& arguments, Int32 arg_count, System.Reflection.MethodBase& method, System.Boolean& params_expanded_form) [0x00000] in <filename unknown>:0

  at Mono.CSharp.ToplevelBlock.Resolve (Mono.CSharp.FlowBranching parent, Mono.CSharp.BlockContext rc, Mono.CSharp.ParametersCompiled ip, IMethodData md) [0x00000] in <filename unknown>:0

导致此问题的代码如下：

Me = new UserAccount(
    name: response["first_name"] as string,
    age:  DateToAge(response["birthday"] as string),
    facebookID: response["id"] as string,
    email: response["email"] as string,
    gender: (response["gender"] as string == "male") ? 0 : 1
);

在哪里＆＃34;回应＆＃34;是Dictionary<string, object>

Dictionary<string, object> response = FacebookHelper.Deserialize(jsonString);

UserAccount类在这里：

public class UserAccount {
    public string SessionKey;
    public string FacebookID;
    public string Name;
    public string Email;
    public int Age;
    public int Gender; 
    public GeoLocation Location;
    public Texture Avatar;

    public UserAccount(string name, int age, int gender, string email = "", GeoLocation location = null, string sessionKey = "", string facebookID = "",  Texture avatar = null) {
        Name = name;
        Email = email;
        Age = age;
        Gender = gender;
        Location = location;
        SessionKey = sessionKey;
        FacebookID = facebookID;
        Avatar = avatar;
    }
}

有人能指出我解决这个问题的正确方向吗？

这是一个真正的编译器错误，已经存在了很长时间。 Unity使用了一个旧的和错误的Mono版本的分支。它发生是因为命名参数。就个人而言，我有时可以使用命名参数，但在某些情况下，它只是在完全正确的代码上崩溃。不幸的是，我能给你的唯一建议是不要在Unity Mono编译器中使用命名参数。

导致InternalErrorException
