用T4模板反射

Question

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);

Answer 1

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.

如果要将名称作为字符串传递，请使用Activator.CreateInstance
