表达式计算器可以计算作为动态而静态键入的变量。
The expression evaluator can evaluate variables that are statically typed as dynamic.
不能指定类，但是可以指定类的成员函数，并让表达式计算器向外搜索。
You cannot specify a class, but you can specify a member function of the class and let the expression evaluator search outward.
使用“表达式计算器外接程序api”来扩展本机调试器表达式计算器。
Uses the expression evaluator Add-In API to extend the native debugger expression evaluator.
我取出了我在第一次谈论这个主题时写作例子的表达式计算器，之后修改了一点代码，增加实时性，如字节码编译。
I took the ExpressionEvaluator I wrote as example for the first post about this topic, and then I edited a bit the code adding just in time AS Bytecode compilation .
该表达式计算器支持具有“通过值传递”的参数的函数调用，但不支持具有“通过引用传递”的参数、对象、数组、函数和字符串的函数调用。
The expression evaluator supports function calls with By Value arguments but does not support function calls with By Reference arguments, objects, arrays, functions, and strings.
