ToBase64String outputBytes ; Console. So the little challenge was to go from a string to a byte array byte[] and clmpress versa without losing a char nor changing its encoding because I ended up finding that System.

Initializes a new instance of the GZipStream class by using the specified stream and compression level, and optionally leaves the stream open. Gets the Type of the current instance. Sign up using Email and Password. Dispose Dispose Dispose Dispose. However, a low-level buffer read such as the following will not work: We’d love to hear your thoughts.

I will edit it. Length not supported Upendra Jagdale Aug Now I know how to save a file using GZipStreambut, my question is not how to do it. Email required Address never made public. By default, GZipStream owns the underlying stream, so closing the stream parameter also closes the underlying stream.

They are not intelligible when renderedand may also cause problems when transmitted over a network due to byte ordering, for instance. Write buffer, 0, buffer. Close Close Close Close. Returns a string that represents the current object. The format can be readily implemented in a manner not covered by patents. CompressionMode is Compress and CanWrite is false.

One way to get this working with very little effort is to introduce a third stream, and copy the GZipStream into it:. Our new feedback system is built on GitHub Issues. NET console application with an exit code Calculate the number of months between two dates with C Convert a dynamic type to a gzipsteam object in. Position Position Position Position. In fact, this problem can be traced to the underlying DeflateStream.

Articles Quick Answers Messages. This code has some problems that already mentioned in other messages below. Close – however, this will also close the underlying stream. The buffer size is probably overkill.

Text to create the byte array and also to change the byte array back into a string. Collect End Function End Class. People who search the web and came to this page may not be concerned about Encoding dropping some letters, or they may even do not believe such a problem exists.
