BLToolkit + T4代+ MySQL數據庫

我收到一個異常運行我的T4模板：BLToolkit + T4代+ MySQL數據庫

Running transformation: System.ArgumentNullException: Value cannot be null. 
Parameter name: type 
    at System.Activator.CreateInstance(Type type, Boolean nonPublic) 
    at Microsoft.VisualStudio.TextTemplatingB9C41E12E53D4F3972EB874C0B96FDFD.GeneratedTextTransformation.GetConnection() 
    at Microsoft.VisualStudio.TextTemplatingB9C41E12E53D4F3972EB874C0B96FDFD.GeneratedTextTransformation.LoadServerMetadata() 
    at Microsoft.VisualStudio.TextTemplatingB9C41E12E53D4F3972EB874C0B96FDFD.GeneratedTextTransformation.LoadMetadata()

    at Microsoft.VisualStudio.TextTemplatingB9C41E12E53D4F3972EB874C0B96FDFD.GeneratedTextTransformation.TransformText() 
    at Microsoft.VisualStudio.TextTemplating.TransformationRunner.RunTransformation(TemplateProcessingSession session, String source, ITextTemplatingEngineHost host, String& result)

這是我的T4文件：

<#@ template language="C#v3.5"   #> 
<#@ output extension=".generated.cs" #> 
<#@ include file="BLToolkit.ttinclude" #> 
<#@ include file="MySql.ttinclude" #> 
<# 
    ConnectionString  = "Server=localhost;Port=3306;Database=accounting;Uid=root;pwd=1;"; 
    DataProviderAssembly = @"D:\Temp\BLToolKitMySql\BLToolKitMySql\mysql.data.dll"; 

    Namespace  = "BLToolKitMySql"; 
    DataContextName = "DataModel"; 
    GenerateModel(); 
#>

我喜歡添加的所有引用：BLtoolkit.3，Bltoolkit .Data.DataProvider.MySql3，mysql.data，sys.data.linq和MySqlDataProvider.cs

什麼是異常和什麼是實際的代碼行？ – pbz 2012-01-31 04:08:36

沒有關於上述error.no文件名的信息，沒有項目名稱，只是第1行和第1列。 – 2012-01-31 06:14:13

似乎MySQL連接不能實例化。我不得不糾正MySql.ttinclude文件：改變

ConnectionType = 「MySql.Data.MySqlClient.MySqlConnection，MySql.Data」;

到

ConnectionType = 「MySql.Data.MySqlClient.MySqlConnection，mysql.data」;
