c# - Runtime compilation generates a file that can't be removed -


i have console type thing accepts line of c# code, wraps in surrounding code , compiles assembly. then, invoke method assembly, output result , that's it.

the problem is, assembly needs have name can set friend assembly access non-public classes. named "console".

everything worked expected problem can't run second script after 1 has finished because file named "console" exists in directory , can't overwritten.

i've tried disposing of has dispose method. i've tried manually deleting file file.delete. nothing helped.

so here's code i'm using. hope can me.

csharpcodeprovider provider = new csharpcodeprovider(); var param = new compilerparameters(); param.generateinmemory = false; param.generateexecutable = false; param.outputassembly = "console"; param.referencedassemblies.add("system.dll"); param.referencedassemblies.add("system.core.dll"); param.referencedassemblies.add(assembly.getexecutingassembly().location); var results = provider.compileassemblyfromsource(param, @" using system; using system.collections.generic; using system.linq; using system.text; using system.io;  namespace fireflygl { class debugconsole {     static void run(stringwriter writer)     {         var stdout = console.out;         console.setout(writer);         " + input.text + @"         console.setout(stdout);     } } }");             if (results.errors.haserrors)             {                 (int = 0; < results.errors.count; ++i)                 {                     pushtext(results.errors[i].errortext);                 }             }             else             {                 try                 {                     var writter = new stringwriter();                     results.compiledassembly.gettype("fireflygl.debugconsole").getmethod("run", bindingflags.static | bindingflags.nonpublic).invoke(null, new object[] { writter });                     pushtext(writter.tostring());                     history.add(input.text);                     currenthistory = history.count;                     input.text = "";                     writter.dispose();                 }                 catch (exception)                 {                  }             }             provider.dispose();             file.delete(results.compiledassembly.location);

you have unload assembly rid of references. unfortunately, can't that. can unload appdomain , provided reference assembly in appdomain, unloaded well.

if don't care creating memory leak, create unique names assembly (console1, console2 etc.)...
