编码转换问题：UCS2码如何转换成GB2312?

[xjjdanran]

如题，应该如何处理？

[xjjdanran]

没人说话了？

[xjjdanran]

虽然问题还没解决，感谢windowslee()的帮助！

又开新贴求助：

最近在做一个短信平台，从运营商处接收到的内容是UCS2编码的
请问在.NET中如何处理？

[hy98521]

up 最近我也在做短信。 不过没碰到过你说的事情啊。

Deliver:(mo)
public string getMsgContent()
{
return Encoding.Default.GetString(this.MsgContent);
}

Submit:(mt)
public void setMsgContent(string strMsgContent)
{


if (this.MsgFormat==0)
{
byte[] b_MsgContent=Encoding.ASCII.GetBytes(strMsgContent);
this.MsgContent=new byte[b_MsgContent.Length];
Buffer.BlockCopy(b_MsgContent,0,this.MsgContent,0,b_MsgContent.Length);
this.MsgLength=(byte)b_MsgContent.Length;
}
if (this.MsgFormat==8)
{
byte[] b_MsgContent=Encoding.BigEndianUnicode.GetBytes(strMsgContent);
this.MsgContent=new byte[b_MsgContent.Length];
Buffer.BlockCopy(b_MsgContent,0,this.MsgContent,0,b_MsgContent.Length);
this.MsgLength=(byte)b_MsgContent.Length;
}
if (this.MsgFormat==15)
{
byte[] b_MsgContent=Encoding.Default.GetBytes(strMsgContent);
this.MsgContent=new byte[b_MsgContent.Length];
Buffer.BlockCopy(b_MsgContent,0,this.MsgContent,0,b_MsgContent.Length);
this.MsgLength=(byte)b_MsgContent.Length;
}

}

我用的是亚信的API开发包，当手机回复时，如果带中文，返回的编码就是UCS2，显示出来就是乱码

[xjjdanran]

windowslee() ：
Deliver返回的消息是UCS2编码，Encoding.Default.GetString(this.MsgContent)还是原样

[windowslee]

你看看SUBMIT的部分,反正就是根据协议在Encoding.xxx几种不同的编码间变换一下
我上边给的代码是小灵通的,我们这边小灵通网关给的编码是固定的,所以我就没有管了,呵呵.

[xjjdanran]

谢谢，我现在做的是移动的，也就那四种编码方式。UCS2对应的值就是8，submit中，对于类型为8的内容，是不是转换成byte[]后再原样复制一遍，然后就以byte[]发送出去？而不是再转换成string，如何转换？

[xjjdanran]

UCS2对应.NET中，究竟是哪个编码方式？

[windowslee]

BigEndianUnicode

这样转换之后还是乱码？？

[fuzi1982]

Response.Clear();
Response.Buffer=true;
Response.AddHeader("Content-Disposition","attachment;filename="+HttpUtility.UrlEncode(ttt,System.Text.Encoding.UTF8)+".xls");
Response.ContentType ="application/vnd.ms-excel";//?置?出文件?型?excel文件。
Response.Charset= "";
this.EnableViewState=false;
System.IO.StringWriter oStringWriter=new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter oHtmlTextWriter=new System.Web.UI.HtmlTextWriter(oStringWriter);
DataGrid1.RenderControl(oHtmlTextWriter);
Response.Write(oStringWriter.ToString());
Response.End();

代码如上：现在的问题是，直接保存，文件名正常，当直接打开时，文件名是乱码~，文件名是日语，是编码的问题么？

[xjjdanran]

非常感谢，问题催得比较急，能转换的话，麻烦你帮我将上面的代码改下吧，好的话，我可以另外开贴再放分。

[xjjdanran]

我们现在是暂时将发送和接收功能实现了，MT消息是中文没问题，API内部处理了吧；可MO时，发送的是字母与数据，也正常，但带了汉字就为乱码了。我们老大还希望下午能带过去给客户演示一番，晕

[windowslee]

我找到我移动的程序了，信息字段对不同编码是这样处理的：
public string getMsg_Content()
{
string strMsg="";
switch(this.getMsg_Fmt())
{
case 15:
strMsg=Encoding.Default.GetString(this.Msg_Content);
break;
case 8:
strMsg=Encoding.BigEndianUnicode.GetString(this.Msg_Content);
break;
case 0:
strMsg=Encoding.ASCII.GetString(this.Msg_Content);
break;

}
return strMsg;

}

[xjjdanran]

自己再UP一下，还请诸位老大们多多帮忙啊

[xjjdanran]

谢谢windowslee(),我问题已经解决了,是我接受短信结构定义不合理,本来应该是byte[]的,接受时强制转换成string了,所以难以在转回来.如果是byte[]可以按你的方法直接转了.
