Asp.net vb.net中此连接字符串的错误是什么？

我有以下连接字符串

<add name="portal_ConnSql" connectionString="Data Source=GFO-SQL03;Initial Catalog=PortalDB_V2;uid=Portal_Usr;Password=20!!P0rt@!"  providerName="System.Data.SqlClient"/>

我得到了以下错误：

at System.Data.Common.DbConnectionOptions.GetKeyValuePair(String connectionString, Int32 currentPosition, StringBuilder buffer, Boolean useOdbcRules, String& keyname, String& keyvalue) at System.Data.Common.DbConnectionOptions.ParseInternal(Hashtable parsetable, String connectionString, Boolean buildChain, Hashtable synonyms, Boolean firstKey) at System.Data.Common.DbConnectionOptions..ctor(String connectionString, Hashtable synonyms, Boolean useOdbcRules) at System.Data.SqlClient.SqlConnectionString..ctor(String connectionString) at System.Data.SqlClient.SqlConnectionFactory.CreateConnectionOptions(String connectionString, DbConnectionOptions previous) at System.Data.ProviderBase.DbConnectionFactory.GetConnectionPoolGroup(String connectionString, DbConnectionPoolGroupOptions poolOptions, DbConnectionOptions& userConnectionOptions) at System.Data.SqlClient.SqlConnection.ConnectionString_Set(String value) at System.Data.SqlClient.SqlConnection.set_ConnectionString(String value) at System.Data.SqlClient.SqlConnection..ctor(String connectionString) at util.getPortalRefelralCode(String referalCode) in E:\sites\EPER EN\App_Code\util.vb:line 280 at Test.Page_Load(Object sender, EventArgs e) in E:\sites\EPER EN\Test.aspx.vb:line 9 at System.Web.UI.Control.OnLoad(EventArgs e) at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) 位于System.Data.Common.DbConnectionOptions.GetKeyValuePair（字符串连接字符串、Int32 currentPosition、StringBuilder缓冲区、布尔useOdbcRules、字符串和键名、字符串和键值） 位于System.Data.Common.DbConnectionOptions.ParseInternal（哈希表parsetable、字符串connectionString、布尔构建链、哈希表同义词、布尔第一键） 位于System.Data.Common.DbConnectionOptions..ctor（字符串连接字符串、哈希表同义词、布尔useOdbcRules） 位于System.Data.SqlClient.SqlConnectionString..ctor（String connectionString） 位于System.Data.SqlClient.SqlConnectionFactory.CreateConnectionOptions（String connectionString，DbConnectionOptions previous） 位于System.Data.ProviderBase.DbConnectionFactory.GetConnectionPoolGroup（字符串connectionString、DbConnectionPoolGroupOptions、DbConnectionOptions和userConnectionOptions） 位于System.Data.SqlClient.SqlConnection.ConnectionString_集合（字符串值） 位于System.Data.SqlClient.SqlConnection.set_ConnectionString（字符串值） 位于System.Data.SqlClient.SqlConnection..ctor（字符串连接字符串） 在E:\sites\EPER EN\App\u Code\util.vb中的util.getportalrefralcode（字符串引用代码）处：第280行 在e:\sites\EPER EN\Test.aspx.vb中的Test.Page\u加载（对象发送方，事件参数e）：第9行 在System.Web.UI.Control.OnLoad（EventArgs e）中 在System.Web.UI.Control.LoadRecursive（）中 在System.Web.UI.Page.ProcessRequestMain（布尔includeStagesBeforeAsyncPoint，布尔includeStagesAfterAsyncPoint）
