When we started it used to take an hour or two, but now it's getting more like 8 when it's working with 164,000 rows :/Īs it was getting to the point where we weren't sure if it was actually doing anything I've put a ticker on the Status Bar that lets us know which row number it is up to so we know it's still working as there was some doubt the first couple of times it got past the three hour mark. We've got this up and running now thanks to the info above, however we've become to increasingly rely on it and the data sets involved have gotten bigger and bigger and it's taking longer and longer to run. In this case, or if the amount of data is so large that it needs to be divided into smaller blocks, use the Decoder or the Encoder provided by the GetDecoder method or the GetEncoder method, respectively.Apologies about bumping the thread, but I've another question about this and to save explaining again. You can remove it by calling the String.TrimStart method.ĭata to be converted, such as data read from a stream, might be available only in sequential blocks. If the range of bytes to be decoded includes the byte order mark (BOM) and the byte array was returned by a method of a non-BOM aware type, the character U+FFFE is included in the character array returned by this method. Without error detection, invalid sequences are ignored, and no exception is thrown. With error detection, an invalid sequence causes this method to throw an ArgumentException exception. To remove the BOM at the beginning of the string, you can call the String.TrimStart method. This means that the two strings will compare as unequal, and that if the string is output, the BOM will be displayed as the replacement character "?". Note that in this case the decoded string differs from the original string, since it begins with a 16-bit byte order mark U+FFFD. ' ?It was the best of times, it was the worst of times. ' The example displays the following output: Utf8.GetBytes(s, 0, s.Length, bytes, utf8.GetPreamble().Length)ĭim s2 As String = utf8.GetString(bytes, 0, bytes.Length) ' We need to dimension the array, since we'll populate it with 2 method calls.ĭim bytes(utf8.GetByteCount(s) + utf8.GetPreamble().Length - 1) As ByteĪrray.Copy(utf8.GetPreamble(), bytes, utf8.GetPreamble().Length) ?It was the best of times, it was the worst of times.ĭim s As String = "It was the best of times, it was the worst of times." The example displays the following output: String s2 = utf8.GetString(bytes, 0, bytes.Length)
Utf8.GetBytes(s, 0, s.Length, bytes, utf8.GetPreamble().Length) We need to dimension the array, since we'll populate it with 2 method calls.īyte bytes = new Byte Īrray.Copy(utf8.GetPreamble(), bytes, utf8.GetPreamble().Length) String s = "It was the best of times, it was the worst of times." UTF8Encoding utf8 = new UTF8Encoding(true, true)
The example then calls the GetString method to decode the string. The example then calls the GetPreamble method to store the BOM to the array before calling the GetBytes method to store the encoded bytes to the array.
The following example initializes an array by calling the GetByteCount method to determine exactly how many bytes are required for an encoded string and then adding the size of the byte order mark (BOM). NET)ĭecoderFallback is set to DecoderExceptionFallback.
