无法在Assembly.LoadFrom方法中加载程序集

Question

I am facing a problem while loading a assembly using Assembly.LoadFrom method. Following is the code.

Assembly theAssembly = default(Assembly);
string PathOfAssembly="C:\\Myapplication\\BasicACHTransmitters.dll";
//Load the assembly into memory
theAssembly = Assembly.LoadFrom(PathOfAssembly);

in the last line theAssembly = Assembly.LoadFrom(PathOfAssembly) I am getting following error.

Unable to load assembly BasicACHTransmitters at M3.AKAP.frmACHSetUp.LoadClasss.LoadClass(String AssemblyName, String ClassName, String InterfaceRequired) in c:\\Builds\\1\\AccKnowledge\\AK3-QA-LS5-Manual\\Sources\\AccKnowledge\\Code\\Ack3.0-QA\\UI\\M3.AKAP\\frmACHSetUp.cs:line 522.

I am unable to find the solution of this and I am stuck now. Please help me to resolve this problem. Any help will appreciated.

Note: The same code is working successfully on another machine with same assembly.

Answer 1

Try using this link using Reflection method. Sample

Answer 2

1.) Try open the file using a reflector tool like just decompile

I would assume the file isn't a .net assembly

2.) If it is a assembly check wether you have the permissions to access the file. If it is a .net policy prevent access and not a windows permission you can Use Caspol.exe to make the file trustworthy For example:

caspol -machine -addfulltrust Z:\myNetworkAssembly.dll
