FXCop / 对带有数组的 WCF DataContract 类进行代码分析 - 创建 CA1819 错误

发布于 2024-10-31 03:07:19 字数 627 浏览 5 评论 0原文

我有以下 WCF 数据协定类：

[DataContract]
public class BinaryResponse : ResponseBase
{
    [DataMember]
    public byte[] Payload { get; set; }
}

很好且简单，完全按照我的需要工作。不过，我现在正在通过完整的代码分析规则集来运行它。这会生成以下警告：

CA1819 : Microsoft.Performance : Change 'BinaryResponse.Payload' to return a collection or make it a method.

查看了此错误的帮助页面解决方案很简单。然而，该解决方案并不真正适合 WCF 数据成员。

所以问题是，如何重构此类，使其仍可用作 WCF 数据契约并通过代码分析？

干杯

I have the following WCF data contract class:

[DataContract]
public class BinaryResponse : ResponseBase
{
    [DataMember]
    public byte[] Payload { get; set; }
}

Nice and simple, works exactly as I need it to. However I am now running this through the full code analysis ruleset. This generates the following warning:

CA1819 : Microsoft.Performance : Change 'BinaryResponse.Payload' to return a collection or make it a method.

Having looked at the help page for this error the solution is a simple one. However the solution doesn't really fit with WCF datamembers.

So the question is, how can I refactor this class to still be useable as a WCF datacontract and also pass the code analysis?

Cheers

您可以将字节数组更改为可枚举或集合，如下所示：

[DataContract]
public class BinaryResponse : ResponseBase
{
    [DataMember] public ICollection<byte> Payload { get; set; }
}

或者您可以将 byte[] 属性保留在私有数组中并将其包装在 ICollection 属性中（如果您需要内部数组）：

[DataContract]
public class BinaryResponse : ResponseBase
{
    // this is NOT a member of the DataContract
    private byte[] payload;

    [DataMember] public ICollection<byte> Payload {
        get { return this.payload; }
        set { this.payload = value.toArray(); }
    }
}

You can do change the byte array to an enumerable or collection, like tehe following:

[DataContract]
public class BinaryResponse : ResponseBase
{
    [DataMember] public ICollection<byte> Payload { get; set; }
}

or you can keep the byte[] attribute in a private array and wrap it in an ICollection property (if you need the internal array):

[DataContract]
public class BinaryResponse : ResponseBase
{
    // this is NOT a member of the DataContract
    private byte[] payload;

    [DataMember] public ICollection<byte> Payload {
        get { return this.payload; }
        set { this.payload = value.toArray(); }
    }
}
