c# - 编译器错误消息 : CS0118: 'System.Configuration.ConfigurationManager.AppSettings' is a 'property' but is used like a 'method'

Question

编译器错误消息:CS0118:“System.Configuration.ConfigurationManager.AppSettings”是“属性”，但像“方法”一样使用

<add key="ObjConn" value="Provider=SQLOLEDB;Persist Security Info=True;User ID=OMembers;PWD=OMembers;Initial Catalog=Db;Data Source=""/>

 strconnection = System.Configuration.ConfigurationManager.AppSettings("ObjConn");
          sqlcon = new SqlConnection(strconnection);

Answer 1

在 C# 中，执行此操作:

strconnection = System.Configuration.ConfigurationManager.AppSettings["ObjConn"];
sqlcon = new SqlConnection(strconnection);
