需要在AutoFixture中注册一个自定义的TypeConverter,用于处理[Column(TypeName = "nvarchar(10)")]类型的属性。示例如下:
public class NvarcharConverter : ICustomization
{
public void Customize(IFixture fixture)
{
fixture.Customizations.Add(new TypeRelay(typeof(string), () => fixture.Create().Substring(0, 10)));
}
}
// 使用示例
var fixture = new Fixture().Customize(new NvarcharConverter());
var entity = fixture.Create();
public class Entity
{
[Column(TypeName = "nvarchar(10)")]
public string Name { get; set; }
}
这样就可以通过AutoFixture生成带有[Column(TypeName = "nvarchar(10)")]属性的实体对象了。
