DynamicVNET 1.4.0-beta

DynamicVNET - Overview

DynamicVNET is .NET Standard library that was created help to develop reuse dynamic validation. It helps to build some rules on POCO and own blackbox libs. It has rich conveniences and features as a <strong>Fluent API</strong> in runtime, wrapped over <strong>DataAnnotation</strong> attributes and supports a cross-platform environment.

Support

• Branching & Nested Branching [synonim logical tree].
• Nested Members.
• Value Types & Single Primitive.
• Reference Types (class).
• Automatic ignoring of repeated validation.
• Strongly Self Validator via Inheritance.

Where is using ?

• POCO Validation.
• Dynamic validation for private libraries (third party libraries 'dll').

Validation methods

• Predicate (Custom)
• StringLen
• EmailAddress
• PhoneNumber
• Url (for GET)
• Required
• MaxLen
• RegularExp
• Range
• Null (Only reference type)
• NotNull (Only reference type)

Example

POCO Models.

public class Employee
{
   public string Name { get; set; }
   public Token TokenNumber { get; set; }
   public string Email { get; set; }
   
}

public class Token
{
   public string Number { get; set; }
}

Validation.

Employee emp = new Employee()
{
    Name = "Jhon", 
    TokenNumber = new Token() { Number = "2312412312341" }, 
    Email = "jhon.sim@gmail.com"
};

var validator = ValidatorFacade.Create<Employee>(builder => {
                    builder.Marker
                            .StringLen(x => x.Name, 4)
                            .EmailAddress(x => x.Email)
                            .Predicate(x => x.Email.Contains("@simple.com"))
                            .Required(x => x.TokenNumber.Number) //  nested member
                            .Required(x => x.TokenNumber.Number); // automatic ignored
                });        

bool result = validator.IsValid(emp);

Detailed Result.

IEnumerable<ValidationMarkerResult> results = validator.Validate(emp);

Branch Example

 var validator = ValidatorFacade.Create<Model>(builder => {
    builder.Marker
            .Required(x => x.Token.TokenNumber)
            .Branch(x => x.Name.Contains("resul"), x =>
             {
                 x.Required(y => y.Email)
                 .StringLen(y => y.Email, 2)
                     .Branch(n => n.Name.Length >= 4,n => {
                          n.MaxLen(s => s.Token.TokenNumber, length: 4);
                       });
            }).Branch(x => x.Email.Contains("aa"), x =>
              {
                  x.Required(y => y.Name)
                  .StringLen(y => y.Name, 5)
                  .StringLen(y => y.Token.TokenNumber, 9);
             });     
 });

Example Strongly Self Validator

public class EmployeeValidator : BaseValidator<Employee>
{
        public EmployeeValidator()
        {
            Setup(builder =>
            {
                builder.Marker
                       .For(x => x.Name)
                       .Required();

                builder.Marker
                      .Branch(x => x.Name.Contains("jhon"), x =>
                      {
                        x.MaxLen(m => m.TokenNumber.Number, 15);
                      })
                      .For(x => x.Email)
                      .Required()
                      .EmailAddress();

                builder.Marker
                     .Required(x => x.TokenNumber.Number);
            });
            
        }
}
 
 Employee emp = new Employee()
{
    Name = "selman:okkes", 
    TokenNumber = new Token() { Number = "adasd123123asd" }, 
    Email = "jhon.sim@jhona.com"
};
 
 
 var empValidator = new EmployeeValidator();
 bool result = empValidator.IsValid(emp);
