  Hi JagjitSingh,

  Please change your code to code below:

  [StringLength(25, ErrorMessage = "The {0} Password length must be at least {2} characters long.", MinimumLength = 3)]

  Due to it can't find the index 3 parmerter .

  Please have a try.

  Best regards,

  Jolie

  Hi JagjitSingh,

  [StringLength(25)] :it means that the min length and max length value both is 25;

  [StringLength(25, ErrorMessage = "The {0} Password length must be at least {2} characters long.", MinimumLength = 3)]:

  It means that the min length  value set as 3  ,the max length value still is 25 .and error message is "The {0} Password length must be at least {2} characters long.",

  And https://referencesource.microsoft.com/#System.ComponentModel.DataAnnotations/Resources/DataAnnotationsResources.Designer.cs,53c08675134a01ce From Microsoft ;

  it tells us that the specify {0} ,{1}or {2} ,not {3} .

  so we can just think the {0} means column name ,the {2} means the min length value, the {1} means the max length value;

  Best regards,

  Jolie
