c# - Programmatically compiling source code using Roslyn -


so i've been trying compile piece of code programmatically roslyn. reasons references add don't end in compilation class. when @ referenced assembly after use 'addreferences', list empty. hence, when try emit, "object" not defined in diagnostics. can point me problem?

microsoft.codeanalysis.syntaxtree syntaxtree = csharpsyntaxtree.parsetext(@" public static class program {     public static void main()     {         system.console.writeline(""hello"");                 } } ");     string autoreferences = @"mscorlib.dll,system.core.dll";     list<string> usings = new list<string>();     string netassembliesdirectory = path.getdirectoryname(typeof(object).assembly.location);     var refs = new list<string>();     foreach (string reference in autoreferences.split(','))         refs.add(netassembliesdirectory + "\\" + reference);       csharpcompilation compilation = csharpcompilation.create("consoletest")         .withoptions(             new csharpcompilationoptions(outputkind.consoleapplication).withusings("system"))         .addsyntaxtrees(syntaxtree);     compilation.addreferences(refs.where(r => r != "").select(r => metadatareference.createfromfile(r)));     var er = compilation.emit(@"c:\" + "consoletest");

roslyn objects immutable.

compilation.addreferences() returns new compilation instance references.
you're ignoring new instance.

you need call emit() on compilation instance has references.

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac
