C#写的Webservice，如何调取Web.config下的配置

1、调取“AppSettings”里的内容

string _hscjHeaderKey = WebConfigurationManager.AppSettings["HttpHeaderKey"];

2、调取数据库连接配置

　　需要先引用“using System;”

        /// <summary>
        /// 本地数据库连接
        /// </summary>
        public static string connectionString = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
