c# - UnityEngine.WWW.WWW(string, byte[], System.Collections.Hashtable)' 已过时

Question

我在更新到 Unity 4.5 后收到过时警告:

Warning CS0618: UnityEngine.WWW.WWW(string, byte[], System.Collections.Hashtable)' is obsolete:This overload is deprecated. Use the one with Dictionary argument.' (CS0618) (Assembly-CSharp)

代码如下:

public class Request {
    public string url;
    public NetworkDelegate del;
    public WWWForm form;
    public byte[] bytes;
    public Hashtable header;

    // Constructors
    public Request(string url, NetworkDelegate del) {
        this.url = url;
        this.del = del;
    }

    public Request(string url, NetworkDelegate del, WWWForm form) : this(url, del) {
        this.form = form;
    }

    public Request(string url, NetworkDelegate del, byte[] bytes) : this(url, del) {
        this.bytes = bytes;
    }

    public Request(string url, NetworkDelegate del, byte[] bytes, Hashtable header) : this(url, del, bytes) {
        this.header = header;
    }

    public WWW makeWWW() {
        if(header != null) {
            return new WWW(url, bytes, header); // problematic line
        }
        if(bytes != null) {
            return new WWW(url, bytes);
        }
        if(form != null) {
            return new WWW(url, form);
        }
        return new WWW(url);
    }
}

我应该如何更改线路？

可以找到原始代码here .

WWW构造函数不期望 Hashtable不再是了，而是一个 Dictionary (它的通用等价物)

按照警告说的做:更换你的Hashtable header成员(member) Dictionary<K,V> , K 是表中 Key 的类型，V 是值的类型。

编辑:

另见 why is Dictionary preferred over hashtable
