Asp.net:  获取虚拟路径地址

HttpContext.Current.Server.MapPath("路径/位置")

将一个数组类型转换为另一个数组类型
Array.ConvertAll<string, int>(majorIDS.Split(‘,‘), s => int.Parse(s))

DbContext写法

public class BaseContext : DbContext
{
public BaseContext()
: base("name=DomeConn")
{

}

public DbSet<Person> Person { get; set; }

public DbSet<NewsEneity> NewsEntity { get; set; }

//生成的实体 去复数s
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
}
}

记录比较杂乱
