1. Question:

In the ASP.NET MVC project, the MaxLength feature is added to a Model as follows:

The copy code is as follows:

Public class SomeClass

{

[MaxLength (16, ErrorMessage = "maximum length 16")]

Public string SomeProperty {get;set;}

}

However, there is no similar data-val-length attribute in its corresponding form element.

Second, the solution: use StringLength instead of MaxLength.

The copy code is as follows:

Public class SomeClass

{

[StringLength (16, ErrorMessage = "maximum length 16")]

Public string SomeProperty {get;set;}

}
