How do I specify the maximum column length of a field using entity framework code first
提问by Kirsten Greed
Is there an attribute I can use when creating a table ? I tried [StringLength]but it seems to be ignored.
创建表时是否有可以使用的属性？我试过了，[StringLength]但似乎被忽略了。
public class EntityRegister
{
public int Id { get; set; }
[StringLength(450)]
public string Name { get; set; }
}
采纳答案by John Woo
alternatively, you can manually do it on Fluent API
或者，您可以手动执行 Fluent API
use HasMaxLength(450)
用 HasMaxLength(450)
or if you want Data Annotation, use MaxLengthand MinLengthattributes
或者如果你想Data Annotation，使用MaxLength和MinLength属性
public class EntityRegister
{
public int Id { get; set; }
[MaxLength(450)]
public string Name { get; set; }
}
