在计算中，一个不完全类型是一种特殊的数据类型，它的定义会跨越多个源文件。在面向对象编程中会由于一些不同的原因用到：性能和成本常常会In computing, a partial type is a data type definition which spans multiple source code files. In object orientated programming this may be necessary for a variety of reasons: performance and cost can often prohibit the use of several separate classes; the use of code generating tools is increasing, and it is convenient to separate machine generated code from code written by the programmer.

不完全类型是C# 2.0的一个特性。用于建立一个不完全类定义的语法如下：Partial types are a feature of the C# 2.0 language. The syntax for creating a partial class definition is as follows:

SourceFile1.cs

public partial class ExampleClass
{
   public void SomeFunction()
   {
       // ...
   }
}

SourceFile2.cs

public partial class ExampleClass
{
   public void SomeOtherFunction()
   {
       // ...
   }
}

在 C# 2.0之前的版本，这会造成一个编译错误，因为同样的类重复定义了两次（同样也因为partial关键字）。在C#2.0中，它会被看作为一个单一的类定义。其它C#2.0的新特性包括匿名方法、迭代子和泛型（类似于C++中的模板）。

使用不完全类对生成的代码没有任何影响（(unless editor meta-data is emitted).

-In C# versions before 2.0, this would cause a compiler error because the same class appears to be defined twice (and also because of the <code>partial</code> keyword). In C# 2.0 this is treated as a single class definition. Other new features of C# 2.0 include [[anonymous methods]], [[iterator]]s and [[generics]] (similar to templates in C++).
-The use of partial classes has no effect on generated code (unless editor meta-data is emitted).
