    copied!<p>stupid me tries to convert a byte-array received from an external source not unter my control to a string. (And yes, I do know about <code>Encoding.GetString(byte[])</code>.</p> <p>What I have so far:</p> <pre><code>void myfunc() { byte[] rawData = new byte[ 128 ]; for( int i = 0; i &lt; rawData.Length; ++i ) { rawData[ i ] = 0; } rawData[ 0 ] = (byte)'H'; rawData[ 1 ] = (byte)'e'; rawData[ 2 ] = (byte)'l'; rawData[ 3 ] = (byte)'l'; rawData[ 4 ] = (byte)'o'; string asString = Encoding.UTF8.GetString( rawData, 0, rawData.Length ); string asRealString = Encoding.UTF8.GetString( rawData ); } </code></pre> <p>Both strings do contain the Hello part but also a lot of \0's afterwards - which is not the thing I expected. The output from the debugger: asRealString = </p> <pre><code>"Hello\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0" </code></pre> <p>Is there any way that would geive me a string like "Hello" ?</p> <p>I did goolge,but all I got was <code>Encoding.GetString(byte[])</code> ...</p> <p><strong>EDIT</strong>: The creatin of the byte array is outside my scope! I do get it as part of a larger, C-Style struct. And there is no leading length of the string. Also I was hoping there iss ome built in way to tdo it and I did not have to find the first \o and tehn convert knowing the length....</p> <p><strong>EDIT</strong> Here is what I used in the end:</p> <pre><code>private static string convertCString( byte[] buffer, int maxLength, Encoding targetEncoding ) { int length = 0; int realMax = buffer.Length &lt; maxLength ? buffer.Length : maxLength; for( ; 0 != buffer[length] &amp;&amp; length &lt; realMax ; ++length ) {} return targetEncoding.GetString( buffer, 0, length ); } </code></pre>
