问题描述
我使用Visual Studio 2013与.NET框架4.5。
I am using Visual Studio 2013 with .NET Framework 4.5.
我已经包括 System.Configuration
。作为项目的引用
I have included the System.Configuration
as a reference in the project.
我也包括using语句在类如:
I have also included a using statement in the class as such:
using System.Configuration;
但是,下面的行仍然给我上述问题的错误。我该如何摆脱错误的?用
However, the following line still gives me the above subject error. How do I get rid of the error?
using (SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["WarrantySqlConnection"].ToString()))
编译时错误是在 ConfigurationManager中
字。
推荐答案
尝试删除并参考重新添加到组装系统.Configuration.dll
,通过引用右击,选择添加引用,然后找到 System.Configuration
。
后添加引用的DLL,如果你有问题,还是保存并关闭Visual Studio和重新启动它。
Try remove and re-add the reference to the assembly System.Configuration.dll
, by right-clicking on the References, choose add reference and then find System.Configuration
.After you add a reference to the dll if you have still problem save and close your Visual Studio and restart it.
