Azure：{“目录路径的语法无效” \\ r \\ n参数名称：initialConfiguration”}错误

Question

I am trying to to add my log file to blob storage. When tried to get the ConnectionString in Global.asax.cs I am getting this error from oriented here :

DiagnosticMonitor.Start("Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString", diagnostics);

How can I fix that problem. "Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString" is in ServiceConfiguration.Cloud.cscfg and ServiceConfiguration.Local.cscfg

To give more explanation :

System.ArgumentOutOfRangeException was unhandled

It looks like you are retrieving the connection string correctly, but your diagnostics configuration is invalid. What are you setting for Directory configurations?

Instead of setting diagnostics configuration via code I would recommend using the wadcfg file ( http://msdn.microsoft.com/en-us/library/windowsazure/hh411551.aspx ), or use Visual Studio (see http://weblogs.asp.net/scottgu/archive/2013/04/30/announcing-the-release-of-windows-azure-sdk-2-0-for-net.aspx , in particular the "Cloud Services: Improved Diagnostics Support" section).
