Question

I have this setting in my model:

[StringLength(250)]
public string Comment { get; set; }

to set the maximum length to 250 in the database which is great.

However it’s set as nvarchar(250) when the database person was expecting varchar(250).

Can somebody please tell me how to set it as a varchar from the model as opposed to an nvarchar?

Answer 1

Use ColumnAttribute to give the datatype

[Column(TypeName = "VARCHAR")]
[StringLength(250)]
public string Comment { get; set; }

Or use fluent API

modelBuilder.Entity<MyEntity>()
  .Property(e => e.Comment).HasColumnType("VARCHAR").HasMaxLength(250);
