Java ikvm未处理的异常：System.TypeLoadException

我是IKVM的新手。我刚刚用JXL依赖jar创建了java项目，用于读取和写入excel文件。并使用IKVMC命令将此项目转换为DLL文件

ikvmc { jxl.jar -out:jxl.dll } { Sample.jar -out:sample.dll }

Java代码：

C#代码：

例外情况：

Exception thrown: 'System.TypeLoadException' in jxl.dll
An unhandled exception of type 'System.TypeLoadException' occurred in 
jxl.dllMethod 'thenComparing' in type 'ColumnInfoComparator' from assembly 
'jxl, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' does not have 
an implementation.

例外情况：

Exception thrown: 'System.TypeLoadException' in jxl.dll
An unhandled exception of type 'System.TypeLoadException' occurred in 
jxl.dllMethod 'thenComparing' in type 'ColumnInfoComparator' from assembly 
'jxl, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' does not have 
an implementation.

你能帮我解决这个问题吗。如何使用IKVM在c-sharp中添加依赖jar
