Your question is far too vague to answer.  Are you a developer?  Are you building a web application?  If so, what technology are you using?  MVC?  Web Forms?  ASP.NET Core?

MVC

Now that we know you are building an MVC application, explain the problem you are trying to solve using a several sentences.  One word responses are not acceptable and rude.   

Share code that is causing this issue.  Explain the expected results and the actual results.

Generally, this type of logic is handled in a security API.  Please share your security API or relevant code. 

Keep in mind, MVC comes out-of-the-box with this capability using the "Individual Account" option when creating a project.

To make the identity aware of the rule you do that when configuring your app (ConfigureServices method)

services.AddIdentity<ApplicationUser, IdentityRole>(options =>
            {
                options.Password.RequiredLength = 8;
                options.Password.RequireDigit = true;
                options.Password.RequireLowercase = true;
                options.Password.RequireUppercase = true;
                options.Password.RequireNonAlphanumeric = true;
            });
