web.config 数据库连接失误

web.config 数据库连接出错
将   SqlConnection   myconn   =   new   SqlConnection(strConn);里的strConn直接用
"Server=ZEMU-A12\COMPANY;UID=zbr;PWD=#szzemucompany#;Database=dbok "   代替运行没有问题，但如果读取web.config中的 <add   key= "strConnString "   value= "Server=ZEMU-A12\COMPANY;UID=zbr;PWD=#szzemucompany#;Database=dbok "> </add>   中的strConnString值时则报     “实例失败”   的错误,请教原因
      protected   static   string   strConn   =   System.Configuration.ConfigurationManager.AppSettings[ "strConnString "];
               
                public   static   int   ExecuteSql(string   strSql)
                {
                        SqlConnection   myconn   =   new   SqlConnection(strConn);
                        SqlCommand   mycomm   =   new   SqlCommand(strSql,   myconn);
                        try
                        {
                                myconn.Open();
                                mycomm.ExecuteNonQuery();
                                return   0;
                        }
                        catch   (System.Data.SqlClient.SqlException   e)
                        {
                                throw   new   Exception(e.Message);
                        }
                        finally
                        {
                                mycomm.Dispose();
                                myconn.Close();
                        }
                }

Web.Config   文件内容:

<?xml   version= "1.0 "   encoding= "utf-8 "   ?>
<configuration>
    <appSettings>
        <add   key= "strConnString "   value= "Server=ZEMU-A12\COMPANY;UID=zbr;PWD=#szzemucompany#;Database=dbok "> </add>
        <add   key= "WebSiteVersion "   value= "Ver1.0 "> </add>
        <add   key= "WebManger "   value= "Windxf "> </add>
    </appSettings>
</configuration>

[解决办法]
<add key= "strConnString " value= "Server=ZEMU-A12\COMPANY;UID=zbr;PWD=#szzemucompany#;Database=dbok "> </add>

后面的 </add> 直接换成/> 试试看
[解决办法]
protected static string strConn = System.Configuration.ConfigurationManager.AppSettings[ "strConnString "];
换成
protected static string strConn = System.Configuration.ConfigurationSettings.AppSettings[ "strConnString "];
试试
[解决办法]
是不是，传入日sql 语句有问题？
[解决办法]
protected static string strConn = System.Configuration.ConfigurationSettings.AppSettings[ "strConnString "];
同意这个方法但是要引入一个命名空间，查一下就知道了


[解决办法]
strConn=ConfigurationSettings.AppSettings( "strConnString ")
[解决办法]
<configuration>
<appSettings>
<add key= "conString "
value= "Server=localhost;UID=sa;PWD=secret;Database=Northwind " />
</appSettings>
</configuration>

-------------------------
string strConString = ConfigurationSettings.AppSettings[ "conString " ];

[解决办法]
<configuration>
<appSettings>
<add key= "msn " value= "server=127.0.0.1;uid=sa;pwd=sa;database=BookShop " />
</appSettings>
</configuration>

string strConString = ConfigurationSettings.AppSettings[ "msn " ];

也许 这个行，你试试吧！
[解决办法]
<appSettings>
<add key= "connstr " value= "server=.;uid=zbr;pwd=#szzemucompany#;database=dbok " />
</appSettings>

--------------------
public static string ConnStr=System.Configuration.ConfigurationSettings.AppSettings[ "ConnStr "];


如果再不行，就不是这方面的问题.
[解决办法]
ding
[解决办法]
using System.Configuration;
public static int ExecuteSql(string strSql)
{
SqlConnection myconn = new SqlConnection(System.Configuration.ConfigurationSettings.AppSettings[ "ConnStr "]);
SqlCommand mycomm = new SqlCommand(strSql, myconn);
