Answer 1

<Script language="C#" runat="Server">
//全角转半角：BigToSmall(yourString,"1"));
//半角转全角：BigToSmall(yourString,"-1"));
private string BigToSmall(string content,string direction)
{
    string strBig,to_strBig;
    strBig ="ＡＢＣＤＥＦＧＨＩＪＫＬＭＮＯＰＱＲＳＴＵＶＷＸＹＺ０１２３４　＇﹃﹄『』＄／ａｂｃｄｅｆｇｈｉｊｋｌｍｎｏｐｑｒｓｔｕｖｗｘｙｚ．５６７８９＊";
    to_strBig = "ABCDEFGHIJKLMNOPQRSTUVWXYZ01234 '“”“”$/abcdefghijklmnopqrstuvwxyz.56789*";
    int i;
    for(i=0;i<strBig.Length;i++)
    {
        if(direction!="-1")
        {
            content=content.Replace(strBig[i],to_strBig[i]);
        }
        else
        {
            content=content.Replace(to_strBig[i],strBig[i]);
        }
    }
    return content;
}
</Script>

Answer 2

      byte[] c=System.Text.Encoding.ASCII.GetEncoder();
char[] c=strline.ToCharArray();
for (int i=0;i<c.Length;i++)
{
byte[] b=System.Text.Encoding.Unicode.GetBytes(c,i,1);
if (b.Length==2)
{
if (b[1]==0)
{
b[0]=(byte)(b[0]-32);
b[1]=255;
c[i]=System.Text.Encoding.Unicode.GetChars(b)[0];
}
}
}
//半角
string strNew=new string(c);这是转贴。

谢谢啦！  方法ok 但是strBig和 to_strBig 的字符集不够  哪有半角和全角字符对比表
