+The following table lists the additional commandline options available for the C# module. They can also be seen by using: +
+ ++swig -csharp -help +
| C# specific options | +|
|---|---|
| -dllimport <dl> | +Override DllImport attribute name to <dl> | +
| -namespace <nm> | +Generate wrappers into C# namespace <nm> | +
| -noproxy | +Generate the low-level functional interface instead of proxy classes | +
| -oldvarnames | +Old intermediary method names for variable wrappers | +
| -outfile <file> | +Write all C# into a single <file> located in the output directory + | +
+The -outfile option combines all the generated C# code into a single output file instead of creating multiple C# files. +The default, when this option is not provided, is to generate separate .cs files for the module class, +intermediary class and each of the generated proxy and type wrapper classes. +Note that the file extension (.cs) will not be automatically added and needs to be provided. +Due to possible compiler limits it is not advisable to use -outfile for large projects. +
