如何使用EF6获取SQL Server列大小

public class YourDbContext : DbContext
{
    public DbSet<YourEntity> YourEntities { get; set; }

    // 在此处配置数据库连接字符串等其他选项
}

public class YourEntity
{
    public int Id { get; set; }
    public string Name { get; set; }
    // 其他属性
}

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
    modelBuilder.Entity<YourEntity>().ToTable("YourTableName");
    // 其他配置代码
}

using (var context = new YourDbContext())
{
    var objectContext = ((IObjectContextAdapter)context).ObjectContext;
    var entityType = objectContext.MetadataWorkspace
        .GetItems<EntityType>(DataSpace.CSpace)
        .FirstOrDefault(e => e.Name == "YourEntity");

    if (entityType != null)
    {
        var properties = entityType.Properties;

        foreach (var property in properties)
        {
            // 获取列的大小
            var storeType = property.TypeUsage.EdmType.Name;
            // 处理 storeType 变量，根据需要进行操作
        }
    }
}
