我写一个简单的名单,其中,T> 以CSV转换器。我将检查所有的 T 的名单中,并抓住所有的公共属性和它们放到CSV。

I am writing a simple List<t> to CSV converter. My converter checks the all the t's in List and grabs all public properties and places them into the CSV.

我的code的伟大工程(如预期),当您将使用一个简单类的一些属性。

My code works great (as intended) when you will use a simple class with a few properties.

我想获得的名单,其中,T&GT; 来CSV转换器也接受了系统的类型,比如字符串和整数。有了这些系统类型,我不想让自己的公共属性(如长度,字符数等)。因此,我想检查,如果对象是一个系统类型。按系统类型我的意思是一个内置的.NET类型,例如字符串,INT32,双等。

I would like to get the List<t> to CSV converter to also accept the System types such as String and Integer. With these system types I do not want to get their public properties (such as Length, Chars etc). Thus I would like to check if the object is a System type. By System type I mean one of the built in .Net types such as string, int32, double etc.

使用的GetType()我可以找到以下内容:

Using GetType() I can find out the following:

string myName = "Joe Doe";

bool isPrimitive = myName.GetType().IsPrimitive; // False
bool isSealed = myName.GetType().IsSealed; // True 
// From memory all of the System types are sealed.
bool isValueType = myName.GetType().IsValueType; // False

// LinqPad users: isPrimitive.Dump();isSealed.Dump();isValueType.Dump();

我怎么能找到,如果MyName变量是一个内置的系统类型? (假设我们不知道它的字符串)

How can I find if variable myName is a built in System type? (assuming we don't know its a string)

推荐答案

myName.GetType()。命名空间 这将返回系统,如果它是一个内置式。

myName.GetType().Namespace This will return System if it is an in-built type.
