Original: MVC authentication 12-use dataannotationsextensions to validate integers, messages, minimums, file types, URL addresses, and more

This article experiences from http://dataannotationsextensions.org/ DATAANNOTATIONSEXTENSIONS.MVC3, which is an extension of dataannotation, can perform two-step verification on both the client and the server, and the types that can be verified include:

Message Verification
Integral type Verification
Date validation
Digital validation (that is, zero-based numbers, excluding with decimal points)
Whether the same validation
File type validation
int type validation (can be negative int type)
Maximum numeric validation (values can be with decimal points, can be validated against negative numbers)
Minimum numeric validation (values can be with decimal points, can be validated against negative numbers)
Numeric validation (can be negative, can take decimal points, or cannot be a string)
URL address Verification
Year validation
......

-Installation

References → Right click → select "Manage nuget packages" → enter "dataannotationsextensions" search → install "dataannotationsextensions.mvc3"

2 files need to be introduced at the same time, dataannotationsextensions for server-side validation, DATAANNOTATIONSEXTENSIONS.MV3 User Client authentication:

When introduced, the reference folder includes:

In addition, do not be confused by the name of Dataannotationsextensions.mv3, under the MVC4 can still be used.

Verify message, Integer, minimum, file type
