实体框架4图像类型

Question

I am using Entity Framework 4 code-first with SQL Server CE 4.

What is the type I should define in the class? SQL Server CE only support Image .

Thank you.

Answer 1

You should use byte[] in your class.

The "image" db type is a bit misleading, as it just represents arbitrary binary data (full SQL Server has deprecated it in favor of the varbinary(max) type)

In your context class, you can try:

modelBuilder.Entity<YourClass>().Property(x => x.YourProperty)
            .HasColumnType("image").IsMaxLength();

(I don't have any SQLCE projects to try it; maybe it will work, maybe not, maybe only one of the configuration methods is enough)
