我目前在涉及 C# 中的静态字段时遇到问题，问题在于 EasyPost 实例化其 ClientManger 的方式，但是，我认为对静态字段有更好理解的人可能会帮助我。

我正在创建一个插件，允许多个用户访问 EasyPost 以跟踪包裹。

我编写了一个单元测试来测试多人同时使用它的场景。

单元测试：

[TestMethod()]
public void TestMultiInit()
    {
        var Client2 = new cpEasyPost("123");
        var Client = new cpEasyPost("123456qq785412");

        var Shipment = Client.CreateShipment(
             new EasyPost.Address
             {
                 street1 = "417 MONTGOMERY ST",
                 street2 = "FLOOR 5",
                 city = "SAN FRANCISCO",
                 state = "CA",
                 zip = "94104",
                 country = "US",
                 company = "EasyPost"
             },
             new EasyPost.Address
             {
                 street1 = "417 MONTGOMERY ST",
                 street2 = "FLOOR 5",
                 city = "SAN FRANCISCO",
                 state = "CA",
                 zip = "94104",
                 country = "US",
                 company = "EasyPost"
             },
             new EasyPost.Parcel
             {
                 length = 20.2,
                 width = 10.9,
                 height = 5,
                 weight = 65.9
             });

        var Shipment2 = Client2.CreateShipment(
             new EasyPost.Address
             {
                 street1 = "417 MONTGOMERY ST",
                 street2 = "FLOOR 5",
                 city = "SAN FRANCISCO",
                 state = "CA",
                 zip = "94104",
                 country = "US",
                 company = "EasyPost"
             },
             new EasyPost.Address
             {
                 street1 = "417 MONTGOMERY ST",
                 street2 = "FLOOR 5",
                 city = "SAN FRANCISCO",
                 state = "CA",
                 zip = "94104",
                 country = "US",
                 company = "EasyPost"
             },
             new EasyPost.Parcel
             {
                 length = 20.2,
                 width = 10.9,
                 height = 5,
                 weight = 65.9
             });


    }

问题是 Client2 的密钥不正确，所以如果我尝试使用它创建一个货件应该会失败，但是因为 ClinetManager 是静态的，所以使用它的客户端初始化，因为如果是稍后。

这是我的演员：

public cpEasyPost(string secretKey)
    {            
        SecretKey = secretKey;
        //Original way of init Client
        //ClientManager.SetCurrent(SecretKey);

        //Create ClientManager
        ClientManager.SetCurrent(() => new Client(new ClientConfiguration(SecretKey)));
    }

这是我的方法：

 public Shipment CreateShipment(Address AddressFrom, Address AddressTo, Parcel Parcel, CustomsInfo customs = null, string CustomReference = "", double? InsauranceAmount = null)
    {
        //Validate Adress
        var isValidFrom = ValidateAddress(AddressFrom);
        var isValidTo = ValidateAddress(AddressFrom);

        if (!isValidFrom.isSuccess)
            throw new Exception("Address From is not Valid");

        if (!isValidTo.isSuccess)
            throw new Exception("Address To is not Valid");

        //Validate Pacrcel
        var isValidParcel = ValidateParcel(Parcel);

        if (!isValidFrom.isSuccess)
            throw new Exception("Parcel is not Valid");

        //Create Shipment
        Shipment shipment = new Shipment()
        {
            reference = CustomReference,
            to_address = AddressTo,
            from_address = AddressFrom,
            parcel = Parcel,
            customs_info = customs            
        };

        //ClientManager.SetCurrent(SecretKey); **
        shipment.Create();

        //Add Insurance
        if (InsauranceAmount != null)
            shipment.Insure(InsauranceAmount.Value);

        return shipment;

    }

不，我遇到的问题是 ClinetManager 是静态的，这是一个锁定的 DDL，所以我无法修改它。在该方法中，我考虑在每次通话之前设置经理，但这似乎不是最好的解决方案，因为理论上它仍然可能导致我用**标记的问题。

任何帮助将不胜感激。谢谢你。

最后，我只是将他们的 SDK 中的代码重新构建成更适合我需要的东西。没有其他方法可以解决这个问题。
