javascript - 将 JavaScript 转换为 C# - 混淆

Question

我有以下 Javascript 代码，需要转换为 C#

function obfuscateApiKey(timestamp, key) {
    var high = timestamp.substring(timestamp.length - 6);
    var low = (parseInt(high) >> 1).toString();
    var apiKey = "";


    while (low.length < 6) {
        low = "0" + low;
    }
    for (var i = 0; i < high.length; i++) {
        apiKey += key.charAt(parseInt(high.charAt(i)));
    }
    for (var j = 0; j < low.length; j++) {
        apiKey += key.charAt(parseInt(low.charAt(j)) + 2);
    }
        console.log(apiKey)
    return apiKey;
}

我已经在 C# 中开始了下面的转换，但我一直在转换

apiKey += key.charAt(parseInt(high.charAt(i)));

var timestamp = DateTime.Now.ToString();
var high = timestamp.Substring(timestamp.Length - 6);
var low = (Int32.Parse(high) >>1).ToString();
while (low.Length < 6)
{
    low = "0" + low;
}
for (var i = 0; i < high.Length; i++)
{
    char ch = (int.Parse(high)[i]); //Getting stuck here! < this is incorrect.
}

Answer 1

你在(high)[i]处犯了错误，尝试high[i]你正在将char转换为int，然后将其分配给char。

var apiKey = "";
var timestamp = DateTime.Now.ToString();
var high = timestamp.Substring(timestamp.Length - 6);
var low = (Int32.Parse(high) >>1).ToString();
while (low.Length < 6)
{
    low = "0" + low;
}
for (var i = 0; i < high.Length; i++)
{
    apiKey += high[i]; 
}

以及您的评论char ch = low[j] + 2

apiKey  += (Convert.ToInt32(low[j]) + 2).ToString();
