ca2202: not dispose objects multiple times 1 reply

i have next code (as example):

using(stream s = new filestream(path)) using(gzipstream gz = new gzipstream(s, compressionmode.compress)) { //do stuff here }

i getting ca2202 "do not dispose objects multiple times" error here. because don't utilize leaveopen parameter in gzipstream?

i have gotten similar errors elsewhere single using statement, apparently multiple calls dispose().

is same problem this question, or else?

because gzipstream disposes of stream. prepare either utilize leaveopen parameter on constructor (which doesn't create much sense in case since want closed anyway) or combine statements:

using(var gz = new gzipstream(new filestream(path), compressionmode.compress)) { // stuff here }
