如何在C#中集成Lua脚本

    //Evaluating simple expressions:
    //Lua can return multiple values, for this reason DoString return a array of objects
    var res0 = state.DoString("return 10 + 3*(5 + 2)")[0];
    Console.WriteLine($"Output result0:{res0}");

    //Passing raw values to the state:
    double val = 12.0;
    state["x"] = val; // Create a global value 'x' 
    var res1 = (double)state.DoString("return 10 + x*(5 + 2)")[0];
    Console.WriteLine($"Output result1:{res1}");

    //Retrieving global values:
    state.DoString("y = 10 + x*(5 + 2)");
    double y = (double)state["y"]; // Retrieve the value of y
    Console.WriteLine($"Y result:{y}");    
    
    Console.ReadKey();
   }
  }}

class Program
 {
  static void Main(string[] args)
  {
   using (var state = new Lua())
   {
    //Retrieving Lua functions:
    state.DoString(@"function ScriptFunc (val1, val2)
           if val1 > val2 then
            return val1 + 1
           else
            return val2 - 1
           end
          end
          ");
    var scriptFunc = state["ScriptFunc"] as LuaFunction;
    var funcRes = scriptFunc.Call(3, 5).First();
    Console.WriteLine($"Func result:{funcRes}");

    Console.ReadKey();
