return void, set field value

[friuns2]

does it support any those?

var typeResolver = new KnownTypeResolver(typeof(Test), typeof(Console));
var test = new Test();
var exprTree = CSharpExpression.Evaluate<Test,int>("test.te=23", test,typeResolver:typeResolver);
throws error Unexpected symbol '='

var exprTree = CSharpExpression.Evaluate<System.void>("Console.Write(123)",typeResolver:typeResolver);
will not work because cannot use System.void

Hi. It is only support expressions. "a=b" is a statement.

"void" returning expressions currently are not supported too. I know it will be bit ugly, but you can wrap "Write" with your method which return something.

Mutation could be done with methods - "test.SetValue(23)"

ok thanks, too bad statements would be usefull :)

I really need this feature, so before I dig into the code to figure out how to add it, is there a strong reason why this is not supported? Thanks!

I really need this feature

Which one?

1. Action expressions (void return type)
2. Statements

[catdawg]

Sorry should have been clearer 😅 the void expressions.

[deniszykov]

Actually not much. New methods for CSharpExpression a few changes in Binder and AotCompiler. I could try to implement it tomorrow.

On the other hand, statements is a huge feature and in the near future I do not plan to implement it.

If you could implement this, I would be extremely likely to use your lib :) Thanks for the fast responses btw!

I have updated NuGet package to version 2.2.0 where Action delegates are supported.
Or you could build from sources 4c49d86. Or wait for Unity Asset Store update.

Cool! I'll try it out, thanks!
