DTSWIZARD 我还找不到 SQL Native Client 入口 哈哈

我的sql2005没有导入导出选项，可能是版本的问题，懒得重装一些软件，我的数据不是很多，这样速度也蛮快的。

为什么不使用SQL Native Client？ 那个速度快很多，最起码在我这边测试是这样的。

有点类似，但本质有很大区别
At the syntax level, C# generics are a simpler approach to parameterized types without the complexity of C++ templates. In addition, C# does not attempt to provide all of the functionality that C++ templates provide.

At the implementation level, the primary difference is that C# generic type substitutions are performed at runtime and generic type information is thereby preserved for instantiated objects.

The following are the key differences between C# Generics and C++ templates:

C# generics do not provide the same amount of flexibility as C++ templates. For example, it is not possible to call arithmetic operators in a C# generic class, although it is possible to call user defined operators.

C# does not allow non-type template parameters, such as template C<int i> {}.

C# does not support explicit specialization; that is, a custom implementation of a template for a specific type.

C# does not support partial specialization: a custom implementation for a subset of the type arguments.

C# does not allow the type parameter to be used as the base class for the generic type.

C# does not allow type parameters to have default types.

谢谢楼上的朋友，加油！！！！

顶起．可以放新手区去咯哈！！！！！！！！！！
