解决方案
解决方案二：
你连接的是远程数据库码？
解决方案三：
不是，本地的.
解决方案四：
不是，本地的.
解决方案五：
把相关代码贴上来看看吧
解决方案六：
ImportsMicrosoft.VisualBasicImportsSystem.Data.SqlClientImportsSystem.DataPublicClassCatalogPublicSharedFunctionGetDepartments()AsSqlDataReaderDimconnectionAsNewSqlConnection(connectionString)DimcommandAsNewSqlCommand("GetDepartments",connection)command.CommandType=CommandType.StoredProcedureconnection.Open()Returncommand.ExecuteReader(CommandBehavior.CloseConnection)EndFunctionPrivateSharedReadOnlyPropertyconnectionString()AsStringGetReturnConfigurationSettings.AppSettings("ConnectionString")EndGetEndPropertyEndClass
解决方案七：
GetDepartments这个函数是如何调用的？
解决方案八：
Returncommand.ExecuteReader(CommandBehavior.CloseConnection)这样返回datareader是不对的。我在本机上测试会报错。command.ExecuteReader这种command类型不应该是Procedure
解决方案九：
up
解决方案十：
我这边倒不是其他的问题，就是connection.Open()报错，刚才贴的就是报错的信息
解决方案十一：
connectionString那把这个内容贴上来吧。还有即使你在这里报错，但是到下面还会报错的
解决方案十二：
我在web.config里面addkey<appSettings><addkey="ConnectionString"value="Server=(local)NetSDK;IntegratedSecurity=True;InitialCatalog=Shop"/></appSettings>
解决方案十三：
连接字符串里怎么没有workstationid呢？添加上去看看可以看看这里的连接字符串介绍www.connectionstrings.com
解决方案十四：
好的，谢谢您啊，我现在就去看看
