在一个旧的应用程序，大部分的字符串属性不能为空，需要的String.Empty有一个默认值。

In a legacy app, most string properties can't be null and need to have a default value of string.empty.

我知道这是可能与迁移做到这一点，但我正在寻找一种方式来做到这一点用流利的配置界面：

I know it's possible to do this with migrations, but I'm looking for a way to do this using the fluent configuration interface:

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        modelBuilder.Properties<string>().Configure(c =>
        {
            c.HasMaxLength(255);

            if (!c.ClrPropertyInfo.IsDefined(typeof (NullableAttribute), false))
            {
                c.IsRequired();
                // I want to set a default value (string.empty) here.
            }
    }

有没有办法做到这一点还是我注定要初始化所有字符串的实体构造？

Is there any way to do this or I'm doomed to initialize all strings in the entity constructors?

推荐答案

现在的答案是是：

AddColumn("[table name]", "[column name]", c => c.Boolean(nullable: false, defaultValue: false));
