<p>Dear developers,</p>
<p>&nbsp;</p>
<p>I get an error when running applications using NPOI under mono: </p>
<p>&nbsp;</p>
<p>Unhandled Exception: System.ArgumentException: Encoding name &#39;UTF-16LE&#39; not supported</p>

Comments: ** Comment from web user: firda **

I have changed it to this while MONO is defined and GOOD_MONO is not (UTF-16 is obviously not working under mono as it should, it is actually working as UTF-16LE which means UTF-16 without BOM)

public static void PutUnicodeLE(String input, byte[] output, int offset)
{
#if !MONO
byte[] bytes = Encoding.GetEncoding("UTF-16LE").GetBytes(input);
Array.Copy(bytes, 0, output, offset, bytes.Length);
#elif GOOD_MONO
byte[] bytes = Encoding.GetEncoding("UTF-16").GetBytes(input);
Array.Copy(bytes, 2, output, offset, bytes.Length - 2);
#else
byte[] bytes = Encoding.GetEncoding("UTF-16").GetBytes(input);
Array.Copy(bytes, 0, output, offset, bytes.Length);
#endif
}
public static void PutUnicodeLE(String input, ILittleEndianOutput out1)
{
byte[] bytes;
try
{
#if !MONO
bytes = Encoding.GetEncoding("UTF-16LE").GetBytes(input);
#else
bytes = Encoding.GetEncoding("UTF-16").GetBytes(input);
#endif
}
catch (EncoderFallbackException)

throw;
}
#if !MONO || !GOOD_MONO

Latest news:
1. Changing the code from Encoding.GetEncoding("UTF-16LE") to Encoding.Unicode works fine in all versions (both .NET and Mono 2.x and should work in Mono 3.x)
2. Fixed in Mono 3.x (beta - not stable yet)

Comments: ** Comment from web user: tonyqus **

This should be a bug in NPOI 1.2.5 because the wrong exception is catched.
private static Record CreateWriteAccess()
{
WriteAccessRecord retval = new WriteAccessRecord();

try
{
retval.Username=(Environment.UserName);
}
catch ( AccessViolationException)
{
// AccessControlException can occur in a restricted context
// (client applet/jws application or restricted security server)
retval.Username=("POI");
}
}
AccessViolationException is not the correct exception to be catched. Instead, SecurityException should be used. This bug will be fixed in NPOI 2.0.

Rated 5 Stars (out of 5) - Very quick and clean solution for my project. I needed to rename the sheets in an Excel document produced by the ReportViewer control. The ReportViewer control only produces the binary Excel format, which NPOI handled without a problem. Thanks for the great work.

This is a known issue. We will try to improve somewhat in the final release of NPOI 2.0. However, the root cause may be the xml serialization in .NET using XmlSerializer. We are looking for alternative solutions for this. In java, POI use XmlBean, which is more efficient than .NET Xml.
