Javascript C# Unicode 字符串 - headscratcher

如果我使用以下方法将 Javascript 中的 Bytearray 转换为字符串：

convertByteArrayToString: function(byteArray)
{
    var s = '';
    for(var i = 0;i < byteArray.length;i++)
            {
                    s += String.fromCharCode(byteArray[i])
            }
    return s;
},

如何将此字符串转换回 C# 中的字节数组？

我已经尝试了以下所有三个：

 System.Text.UnicodeEncoding encoding = new System.Text.UnicodeEncoding().GetBytes(myString);
 System.Text.UTF32Encoding encoding = new System.Text.UTF32Encoding().GetBytes(myString);
 System.Text.UTF8Encoding encoding = new System.Text.UTF8Encoding().GetBytes(myString);

最接近的是第一个，但它返回一个字节数组，该数组是原始长度的两倍，数组中的每个其他元素都是 0，有时是一个或两个不正确的值。

据我所知， String.fromCharCode 在 Unicode 中工作，那么如何让它与 C# 进行互操作呢？

这让我抓狂！

编辑：

这是一个示例，

原始字节数组： [139, 104, 166, 35, 8, 42, 216, 160, 235, 153, 23, 143, 105, 3, 24, 255]

我的函数将其转换为： "h...*Ø ëiÿ"

在 C# 中，尝试将此 String 解码为字节数组会产生以下结果：

使用 System.Text.UnicodeEncoding 给出： [142,0,139,0,104,0,166,0,35,0,8,0,42,0,216,0,32,0,235,0,153,0,23,0,143,0,105,0,30,24,0,255,0]

原文

If I convert a Bytearray in Javascript to a string using the following method:

convertByteArrayToString: function(byteArray)
{
    var s = '';
    for(var i = 0;i < byteArray.length;i++)
            {
                    s += String.fromCharCode(byteArray[i])
            }
    return s;
},

How do I then convert this string back to a byte array in C#?

I have tried all three of the following:

 System.Text.UnicodeEncoding encoding = new System.Text.UnicodeEncoding().GetBytes(myString);
 System.Text.UTF32Encoding encoding = new System.Text.UTF32Encoding().GetBytes(myString);
 System.Text.UTF8Encoding encoding = new System.Text.UTF8Encoding().GetBytes(myString);

The closest is the first one, but it returns a Byte array which is double the length of the original with every other element in the array being 0 and sometimes an incorrect value or two.

As far as I am aware, the String.fromCharCode works in Unicode, so how do get this to interoperate with C#?

This is driving me nuts!

Edit:

Here is an example,

Original Byte array:
[139, 104, 166, 35, 8, 42, 216, 160, 235, 153, 23, 143, 105, 3, 24, 255]

My function converts this to:
"h¦#*Ø ëiÿ"

In C#, attempting to decode this String to a byte array yields the following results:

Using System.Text.UnicodeEncoding gives:
[142,0,139,0,104,0,166,0,35,0,8,0,42,0,216,0,32,0,235,0,153,0,23,0,143,0,105,0,30,24,0,255,0]
