解密base64加密编码，部分中文乱码问题
public static string DecompressGZip(string unCompressedString)
{
---unCompressedString 是压缩加密后的64编码
System.Text.StringBuilder uncompressedString = new System.Text.StringBuilder();
byte[] writeData = new byte[4096];
//将string字符串解码（转换为等效的8位无符号整数数组）
byte[] bytData = System.Convert.FromBase64String(sunCompressedString);

int totalLength = 0;
int size = 0;
//解压缩基础流来创建zip流对象
Stream s = new GZipStream(new MemoryStream(bytData), CompressionMode.Decompress);
while (true)
{
size = s.Read(writeData, 0, writeData.Length);//从当前流读取字节序列
if (size > 0)
{
totalLength += size;
//追加字符串到uncompressedString的结尾处
uncompressedString.Append(System.Text.Encoding.UTF8.GetString(writeData, 0, size));
说明：循环期间每次循环的最后一个字如果是中文，那么这个中文在转换后就是乱码，中间的汉字没发现问题 }
else
{
break;
}
}
s.Close();//关闭流
return uncompressedString.ToString();//返回字符串
}


监狱以上问题，请高手帮忙解决，谢谢~！

[解决办法]
检查unCompressedString是否是utf8编码
[解决办法]
unCompressedString 这个字符串是怎么生成的？
[解决办法]
这样写吧，原来是中文字符被截断所以乱码了

C# code

public static string DecompressGZip(string unCompressedString){    System.Text.StringBuilder uncompressedString = new System.Text.StringBuilder();    byte[] writeData = new byte[4096];    //将string字符串解码（转换为等效的8位无符号整数数组）    byte[] bytData = System.Convert.FromBase64String(sunCompressedString);    int totalLength = 0;    int size = 0;    //解压缩基础流来创建zip流对象    Stream s = new GZipStream(new MemoryStream(bytData), CompressionMode.Decompress);    using (var ms = new MemoryStream())    {        var len = 0;        while ((len = s.Read(writeData, 0, writeData.Length)) > 0)        {            ms.Write(writeData, 0, len);        }        uncompressedString.Append(Encoding.UTF8.GetString(ms.ToArray()));    }    s.Close();//关闭流    return uncompressedString.ToString();//返回字符串}
[解决办法]
4楼代码这个位置打错了，多了个 s
byte[] bytData = System.Convert.FromBase64String(unCompressedString);

[解决办法]
using (var ms = new MemoryStream())
改成
using (MemoryStream ms = new MemoryStream())
[解决办法]
var len = 0;
该成
int len = 0;
