全角转半角：
C# Code:
///转半角的函数(DBC case)
///全角空格为12288，半角空格为32
///其他字符半角(33-126)与全角(65281-65374)的对应关系是：均相差65248//
public static string ToDBC(string input)
{
char[] array = input.ToCharArray();
for (int i = 0; i < array.Length; i++)
{
if (array[i] == 12288)
{
array[i] = (char)32;
continue;
}
if (array[i] > 65280 && array[i] < 65375)
{
array[i] = (char)(array[i] - 65248);
}
}
return new string(array);
