需要一些帮助转换Js到c#

此函数迭代某些对象的可枚举属性(Object.keys)，并将属性值写入字符串-但不包含键和任何分隔符。

我不知道_self.params在这种情况下指的是什么，因为它不是JavaScript固有的，也没有提供它的定义。

直接翻译为c#是不可能的c#/。. NET不使用具有可枚举属性的原型，最接近的模拟是将_self.params表示为Dictionary<Object,String>:

public static String GetParamsAsStr(Dictionary<Object,String> p) {
    if( p == null || p.Count == 0 ) return String.Empty;
    StringBuilder sb = new StringBuilder();
    foreach(Object key in p.Keys) sb.Append( p[key] );
    return sb.ToString();
}

我写这篇文章是为了能够把整个事情…

这是最初的JS代码，它设置了第一个参数，以便稍后进行一些API调用:

    var Signer = function () {
    this.apkId = getApkId();
    this.apkSecret = getApkSecret();
    this.servicio = "";
    this.sessionToken = "";
    this.timestamp = "";
    this.requestId = "";
    this.params = "";
    var _self = this;
    this.getParamsAsStr = function () {
        var keys = Object.keys(_self.params ? _self.params : {});
        keys.sort();
        var response = "";
        for (var i = 0 ; i < keys.length ; i++) {
            response += _self.params[keys[i]];
        }
        return response;
    }
    this.getSignature = function () {
        var baseString = 
            _self.apkSecret +
            _self.servicio +
            _self.sessionToken +
            _self.timestamp +
            _self.requestId +
            _self.getParamsAsStr();
        console.log("Signature pre hash:'n" + baseString);
        baseString = baseString.toLowerCase();
        return sha1(baseString);
    }
}

    public class Signer
{
    public string appId = getApkId();
    public string appSecret = getAppSecret();
    public string servicio = "";
    public string sessionToken = "";
    public string timestamp = "";
    public string requestId = "";
    public string params = "";
    //Here I have to write the getParamsAsStr()
    private static string getApkId(){
        string id = "xxxxxxxxxxxxxxxx";
        return id;
    }
    private static string getAppSecret(){
        string id = "xxxxxxxxxxxxxxxx";
        return id;
    }
}
