How do I specify the maximum column length of a field using entity framework code first

Question

Is there an attribute I can use when creating a table ? I tried [StringLength] but it seems to be ignored.

 public class EntityRegister  {      public int Id { get; set; }      [StringLength(450)]      public string Name { get; set; }  } 

Answer 1

alternatively, you can manually do it on Fluent API

use HasMaxLength(450)

• Configuring Properties and Types with the Fluent API
  • EF 6
  • EF Core

or if you want Data Annotation, use MaxLength and MinLength attributes

public class EntityRegister {     public int Id { get; set; }     [MaxLength(450)]     public string Name { get; set; } } 

• Code First Data Annotations
