ASP.NETvNextCoreCLR缺少type.IsPrimitive-ASP.NETvNextCoreCLRmissingtype.IsPrimitive

I am trying to migrate a web app to ASP.Net vNext with the eventual aim of getting it running on Linux.

我正在尝试将Web应用程序迁移到ASP.Net vNext，最终目的是让它在Linux上运行。

The app has a lot of reflection code and I must be missing some dependencies as I am getting compile errors on code such as this

该应用程序有很多反射代码，我必须缺少一些依赖项，因为我在代码上遇到编译错误

Type.IsPrimitive, Type.GetConstructor Type.GetMethod Type.GetTypeArray Error CS1061 'Type' does not contain a definition for 'IsPrimitive' and no extension method 'IsPrimitive' accepting a first argument of type 'Type' could be found (are you missing a using directive or an assembly reference?)

I have the following dependencies in my project.json files

我的project.json文件中有以下依赖项

"frameworks" : {
    "aspnetcore50" : { 
        "dependencies": {
            "System.Runtime": "4.0.20-beta-22416",
            "System.Linq": "4.0.0.0-beta-22605",
            "System.Reflection": "4.0.10.0-beta-22605",
            "System.Reflection.Primitives": "4.0.0.0-beta-22605",
            "System.Runtime.Extensions": "4.0.10.0-beta-22605",
            "System.Reflection.Extensions": "4.0.0.0-beta-22605"
        }

The following compiles fine under VS 2013 and .Net 4.5 but wont compile in VS 2015 using the dependencies above

以下编译在VS 2013和.Net 4.5下很好，但不会使用上面的依赖项在VS 2015中编译

using System;
using System.Reflection;


namespace Project1
{
    public class Class1
    {
        public Class1()
        {
            Type lBaseArrayType = typeof(Array);
            Type lStringType = typeof(string);
            string[] lStringArray = new string[1];
            if (lStringType.IsPrimitive)
            {
            }
            ConstructorInfo lCOnstructor= lStringType.GetConstructor(new Type[0]);
            MethodInfo lMethod = lStringType.GetMethod("Equals");
            Type[] lTArray = Type.GetTypeArray(lStringArray);
            PropertyInfo[] lProps = lStringType.GetProperties();
        }
    }
}

2 个解决方案

lStringType.GetTypeInfo().IsPrimitive

Type[] types = Type.GetInterfaces()

    var arrayType = typeof(Array);
    var stringType = typeof(string);
    var stringArray = new string[1];
    var stringTypeInfo = stringType.GetTypeInfo();
    if (stringTypeInfo.IsPrimitive)
    {
    }

    ConstructorInfo lCOnstructor= stringTypeInfo.DeclaredConstructors.Where(x => x.GetParameters().Any() == false).FirstOrDefault();
    MethodInfo lMethod = stringTypeInfo.DeclaredMethods.Where(x => x.Name == "Equals").FirstOrDefault();
    Type[] lTArray = stringArray.Where(x => x != null).Select(x => x.GetType()).Distinct().ToArray();
    PropertyInfo[] lProps = stringTypeInfo.DeclaredProperties.ToArray();
