type gettype

This situation is often encountered during development. In Assembly A. dll, the type in assembly B. dll needs to be reflected. A running error occurs if you are not careful with it. For example, if Type. GetType ("BNameSpace. ClassName") is used in

Type. GetType always returns NULL; Later, I checked the reference in the web project and found that there was a reference to the corresponding project .. Therefore, the applicationProgramThe corresponding DLL cannot be found in the web project ..

In the same assembly, type. getType ("Class Name"), you can get this class type, but if it is cross-assembly, you must type. getType ("Class Name, assembly name"), you must add your Assembly name; otherwise, null is obtained. However, system. web.

Generally, we can obtain object types using the following methods: String vtypename = "system. int32 "; Type vtype = type. GetType (vtypename ); Type vtype1 = typeof (INT );   However, when an assembly is dynamically loaded and used in another
