[Захарова Наталья Иркиновна]

Hello!

I try use glpk for c#.

I’m widows 10 and VS 2015 amd 64-bit Windows. But my application is 32 bit.

I add libglpk-cli.dll to project and add libglpk_cli_native and glpk_4_60 to /bin directory.

Test to solve was excellent.

When I try use glpk in me application

 

In GLPK.glp_add_cols(lp, varcounter), when varcounter= big number, for example varcounter=4961

I get exception

'GLPK.glp_add_cols(lp, varcounter)' threw an exception of type 'System.AccessViolationException'
