silverlight IsolatedStorageSettings用法

    silverlight中的IsolatedStorageSettings是一个独立存储空间,可以通过它来实现数据的存储于交互,如实现页面传值。使用前要先引入命名空间:using System.IO.IsolatedStorage;

        /// <summary>
        /// 声明独立存储
        /// </summary>
        private IsolatedStorageSettings appSettings = IsolatedStorageSettings.ApplicationSettings;

 /// <summary>

        /// 将信息加入存储区

        /// </summary>

        public void SetLineInfo()

        {



            if (!appSettings.Contains("RowNumber"))

            {

                appSettings.Add("RowNumber", txtWallRowNumb.Text.Trim());

            }

            if (!appSettings.Contains("ColNumber"))

            {

                appSettings.Add("ColNumber", txtWallColNumb.Text.Trim());

            }



        }

  调用独立存储区中的值:

 if (appSettings.Contains("RowNumber"))

            {

                RowNumber = Convert.ToInt32(appSettings["RowNumber"]);

            }

  清空独立存储区:

appSettings.Clear();
