The previous blog post introduced the profile provider and profile dynamic class,
And some basic content about profile. In this blog,
It also introduces the basic content of profile, that is, adding, deleting, modifying, and querying the profile of a single user,
In addition, deletion, modification, and query, the addition and modification are actually the same thing, but they are a coverage problem between values,
In fact, there is no such change,
The change is only to replace the old value of the corresponding attribute with the new value of the profile attribute,
In fact, there are many ways to delete it, but they are all done through profilemanager,
It can be deleted based on the latest activity time or username,
However, there are several methods to query them,
You can use the dynamically generated class profilecommon to find the profile attribute values of a single user,
You can also use the profilemanager class to complete more powerful search functions,
However, this demo only describes how to search for a single user,
Therefore, dynamic profilecommon is used to complete the process,
However, profilemanager is more powerful,
In this case, list it.MsdnMediumProfilemanagerLet's take a look.

The date of the last activity is the same as or before the specified date and time,
The User Name of the configuration file matches the specified name.

The description here is very clear, so I will not introduce it here. If you don't know it, you can check msdn yourself.
In this demo, the deletion operation is also performed on a single user,
In the demo, the user is deleted using profilemanager. deleteprofile (string username)
The search method uses profilecommon. [attribute name] to directly access the attribute,
For Addition and modification, the profile class is used, and then its profile. Sava () method can be called,
Let's take a look at the demo (first look at adding and modifying)

Then let's take a look at the effect of addition and modification.

In this way, this data exists in the aspnet_profile table of the database,
Under the query function, you can see
Now let's take a look at the query and deletion.

The above section completes the deletion and query of profiles for individuals.
Better results
Search for Xiaozhen first
Then look for chenjing.
Try again to find a profile that has not been defined for it (you can see that there is nothing)
The deletion function is demonstrated.
Delete chenjing first (you can see that the deleted profile attribute values are empty)
Try to delete a profile that has not been set (the profile will be deleted as null)
Through the above demos, we have completed the addition, deletion, modification, and query of personal profiles,
Of course, there are thousands of website users. If they are deleted for individuals,
There will be no dead-end users. If there will be too many anonymous users in the future,
After a period of time, we should delete the profile of an anonymous user who has not been active for a long time,
In this way, the database can be effectively managed,
As mentioned later, I think you can check msdn to solve this problem !!!
