我有一个这种类型的表达式:
Expression<Action<T>> expression
如何从该表达式中获取参数名称(可选: and values)?
示例:
o => o.Method("value1", 2, new Object());
名称可以是str_par1、int_par2、obj_par3
我有两个类UpObj和DownObj
public class UpObj {
public UpObj() {
System.out.println("Load UpObj ");
}
}
public class DownObj extends UpObj {
public DownObj() {
System.out.println("Load DownObj ");
}
}
public class Caller {
UpObj obj;
public Cal
我有一个方法,它有一个输入列表,每个输入值都必须将其转换为必需的类型。(实际上这个列表有一些形式的参数值,我应该将它们转换成必需的类型,必需的类型是方法需要的类型,这是为了通过反射调用api )
我写过这样的代码:
Type[] argTypes = method.getGenericParameterTypes();
List<Object> acutalValues = // List of actual values from method input.
// Resultant list of arguments which will holds casted values
给定以下类...
public abstract class FooBase<TBar> where TBar : BarBase{}
public abstract class BarBase{}
public class Bar1 : BarBase{}
public class Foo1 : FooBase<Bar1> {}
...and下面的方法...
public TBar DoSomething<TFoo, TBar>(TFoo theFoo)
where TFoo : FooBase<TBar>
where TBar
这是最终的产品。如果其他人有什么建议,请告诉我!非常感谢你的帮助!
