.NET和C＃ [英] .NET and C#

问题描述

大家好。

是否在.NET中有任何类，它将.NET数据类型转换为c＃类型？ （即获取一个.NET数据类型的
a变量并返回本机c＃类型？）。

Rgds，

Hi everybody.
Is in .NET any class, which converts .NET data types to c# types? (i.e. gets
a variable of one of .NET data types and returns native c# type?).
Rgds,

他们是一回事。将变量声明为int时或者

" float"，它与写Int32相同。或者单一。


Eq。

They are the same thing. When you declare a variable as "int" or
"float", it''s the same as writing "Int32" or "Single".

Eq.

也许我正在拥有一个慢脑。那一天，但你能澄清一下你的意思吗？


C＃并不真正拥有自己的任何数据类型（它只有编译时间

别名为CLR类型）;类型是相同的 - 即typeof（int）==

typeof（Int32）。


你的意思是名字？即给它System.Int32。它返回int？在

这种情况​​下，我不知道任何内置的东西，但是别名列表并不是
长。你在谈论变量时有点让我失望 - 这是一个

代码生成器吗？

Maybe I''m having a "slow brain" day, but can you clarify what you mean?

C# doesn''t really have any data types of its own (it merely has compile-time
aliases to the CLR types); the types are the same - i.e. typeof(int) ==
typeof(Int32).

Do you mean the names? i.e. give it "System.Int32" and it returns "int"? in
which case I am not aware of anything inbuilt, but the list of aliases isn''t
long. You''re throwing me a bit by talking about variables - is this for a
code generator?

好的，这很清楚，但我在同一个代码中有另一个问题。我想

用system.io的二进制文件写一些数据。该方法有18个版本的b $ b版本，并采用不同数据类型的对象：bool，int等。我有一个常规对象，它有所有类型的数据 - 从数据库中读取。我想要做这样的事情：

对象o = ...

binarywriterobject.write（o as o.getType（））

但当然这是不可能的，因为它就像转换为Type类型。

你知道如何解决这个问题吗？

Rgds，

OK, that''s clear, but I have another problem in the same code. I want to
write some data with binarywriter from system.io. That method has 18
versions and takes object of different data types: bool, int, and so on. I
have a regular object, which has data of all types - read from database. I
want to make something like this:
Object o =...
binarywriterobject.write(o as o.getType())
But of course it''s not possible, because it''s like convertion to Type type.
Have you any idea how to solve this?
