c# - Log4Net 数据库乐趣 - 连接字符串!

Question

这适用于开发人员:

 <connectionString name="asdf" value="Data Source=.\;Initial Catalog=fmwebapp1;Integrated Security=True" />
      <connectionType value="System.Data.SqlClient.SqlConnection, System.Data, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />

在实时(64 位 VPS)上这不起作用:

<connectionString value="CT210991\SQLEXPRESS;Initial Catalog=fmwebapp1;Integrated Security=True" />
      <connectionType value="System.Data.SqlClient.SqlConnection, System.Data, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />

错误是:

log4net:ERROR [AdoNetAppender] Could not open database connection [CT210991\SQLEXPRESS;Initial Catalog=fmwebapp1;Integrated Security=True]
System.ArgumentException: Keyword not supported: 'ct210991\sqlexpress;initial catalog'.

   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 log4net.Appender.AdoNetAppender.InitializeDatabaseConnection()

大脑变得模糊..64 位问题？

Answer 1

您的连接字符串值中的“CT210991\SQLEXPRESS”前面没有“Data Source=”。
