上面我搞错了下面是MSDN的代码，用法可以参照下列代码看看是否有错误，如果代码没有问题，应该是数据的问题。我估计很可能是代码有问题 建议 1）将一个字符串转化为ISO-8859-1后作为源，看你的程序能否正常转化为gb2312显示 using System; using System.Text;namespace ConvertExample { class ConvertExampleClass { static void Main() { string unicodeString = "This string contains the unicode character Pi(\u03a0)"; // Create two different encodings. Encoding ascii = Encoding.ASCII; Encoding unicode = Encoding.Unicode; // Convert the string into a byte[]. byte[] unicodeBytes = unicode.GetBytes(unicodeString); // Perform the conversion from one encoding to the other. byte[] asciiBytes = Encoding.Convert(unicode, ascii, unicodeBytes);
// Convert the new byte[] into a char[] and then into a string. // This is a slightly different approach to converting to illustrate // the use of GetCharCount/GetChars. char[] asciiChars = new char[ascii.GetCharCount(asciiBytes, 0, asciiBytes.Length)]; ascii.GetChars(asciiBytes, 0, asciiBytes.Length, asciiChars, 0); string asciiString = new string(asciiChars); // Display the strings created before and after the conversion. Console.WriteLine("Original string: {0}", unicodeString); Console.WriteLine("Ascii converted string: {0}", asciiString); } } }
