我要加密數據庫中的地址,它也不例外撲救,但是當我負載解密地址提示錯誤:解密個人地址給出錯誤asp.net
Unable to load information. Possible reason: Error in DecodeInvalid length for a Base-64 char array.
<asp:TextBox ID="txtAddress" runat="server" Width="200px" />
<ajaxToolkit:FilteredTextBoxExtender ID="ftxtAddress" runat="server" TargetControlID="txtAddress"
FilterType="Custom,Numbers, LowercaseLetters" InvalidChars="[email protected]#$%^&*()~`*-/+|\}{[]<>?" ValidChars=",.?-_ " />
我用:
public string Decode(string sData)
{
try
{
System.Text.UTF8Encoding encoder = new System.Text.UTF8Encoding();
System.Text.Decoder utf8Decode = encoder.GetDecoder();
byte[] todecode_byte = Convert.FromBase64String(sData);
int charCount = utf8Decode.GetCharCount(todecode_byte, 0, todecode_byte.Length);
char[] decoded_char = new char[charCount];
utf8Decode.GetChars(todecode_byte, 0, todecode_byte.Length, decoded_char, 0);
string result = new String(decoded_char);
return result;
}
catch (Exception e)
{
throw new Exception("Error in Decode" + e.Message);
}
}
你可以顯示你的代碼在哪裏做編碼?或者給我們一個給出錯誤的sData的例子? –
