反射用T4模板

问题描述

我有一个名为的VideoGame 模型类。我需要的类在这个方法中使用反射获得通过在T4模板。

 的MethodInfo [] = methodInfos
    typeof运算（类型）.GetMethods（BindingFlags.Public | BindingFlags.Static）;
 

我有以下变量。

  //通过PowerShell的文件中传递 - 是一个字符串的VideoGame
VAR MODELNAME = Model.modelName
类型type = modelName.GetType（）;
 

我得到一个错误，指出：类型或命名空间名称'类型'找不到（是否缺少using指令或程序集引用？）。我需要知道的是如何传递的typeof（）方法中视频游戏类。我曾尝试以下内容：

 的MethodInfo [] = methodInfos
    。typeof运算（modelName.GetType（））的getMethods（BindingFlags.Public | BindingFlags.Static）;
MethodInfo的[] methodInfos =
    modelName.GetType.GetMethods（BindingFlags.Public | BindingFlags.Static）;
MethodInfo的[] methodInfos =
    typeof运算（MODELNAME）.GetMethods（BindingFlags.Public | BindingFlags.Static）;
 

解决方案

typeof运算（modelName.GetType（））永远不会成功，因为modelName.GetType（）返回以System.String的运行时类型。

modelName.GetType有同样的问题。

typeof运算（MODELNAME）不会起作用，因为MODELNAME是字符串，typeof运算需要一个类型。

所以....如果你有一个字符串的VideoGame，你想要得到的类型的VideoGame方法....

我会做：

  Type.GetType（MODELNAME）.GetMethods（）
 

Type.GetType将由指定名称返回一个类型。请注意，这需要一个大会限定名称....所以才提供的VideoGame是不够的。你需要MODELNAME是形式：

  MyNamespace.VideoGame，MyAssemblyThatContainsVideoGame
 

此外，这意味着，无论是运行您的T4 code需要具有MyAssemblyThatContainsVideoGame一个参考。

I have a model class called VideoGame. I need the class to get passed in a t4 template using reflection in this method.

MethodInfo[] methodInfos =
    typeof(type).GetMethods(BindingFlags.Public | BindingFlags.Static);

I have the following variables.

//passed via powershell file - is a string "VideoGame"
var modelName = Model.modelName
Type type = modelName.GetType();

I get an error that says: The type or namespace name 'type' could not be found (are you missing a using directive or an assembly reference?). What I need to know is how to pass the VideoGame class inside that typeof() method. I have tried the following:

MethodInfo[] methodInfos =
    typeof(modelName.GetType()).GetMethods(BindingFlags.Public | BindingFlags.Static);
MethodInfo[] methodInfos =
    modelName.GetType.GetMethods(BindingFlags.Public | BindingFlags.Static);
MethodInfo[] methodInfos =
    typeof(modelName).GetMethods(BindingFlags.Public | BindingFlags.Static);

解决方案

typeof(modelName.GetType()) would never work, because modelName.GetType() returns a System.String's runtime type.

modelName.GetType has the same problem.

typeof(modelName) won't work because modelName is a string and typeof expects a Type.

So....if you have a string "VideoGame" and you want to get the methods on the Type VideoGame....

I would do:

Type.GetType(modelName).GetMethods()

Type.GetType will return a Type by the specified name. NOTE that this requires an Assembly Qualified Name....so just supplying VideoGame isn't enough. You need modelName to be in the form:

MyNamespace.VideoGame, MyAssemblyThatContainsVideoGame

Further, that means that whatever is running your T4 code needs to have a reference to MyAssemblyThatContainsVideoGame.
