企業庫數據塊引發異常

Question

我正在開發一個新應用程序，並使用以下命令通過nuget下載了企業庫：

安裝包EnterpriseLibrary.Data

每當我嘗試調用以下語句時，都會出現以下錯誤：

 Database objDB = DatabaseFactory.CreateDatabase();

例外是

“ /”應用程序中的服務器錯誤。

Database provider factory not set for the static DatabaseFactory. Set a provider factory invoking the DatabaseFactory.SetProviderFactory method or by specifying custom mappings by calling the DatabaseFactory.SetDatabases method. 

我的配置文件如下所示：

 <configSections>

<!--<section name="dataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings, Microsoft.Practices.EnterpriseLibrary.Data, Version=6.0.1304.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="true" ></section>-->
<section name="dataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings, Microsoft.Practices.EnterpriseLibrary.Data"/>

我的連接字符串如下所示：

  <connectionStrings>
<add name="Dbconnection"
   connectionString="Server=SQL100; Database=Test_db ; Trusted_Connection=Yes; "
   providerName="System.Data.SqlClient"   />

我創建的用於調用存儲過程的方法如下：

 string connStr = ConfigurationManager.AppSettings["ConnString"].ToString();
 DataSet ds = new DataSet();

        Database objDB = DatabaseFactory.CreateDatabase();

        DbCommand cmd;

        try

        {

            cmd = objDB.GetStoredProcCommand("sp_PubTables");



            ds = objDB.ExecuteDataSet(cmd);

            return ds;


        }

        catch (Exception ex)

        {

            throw ex;

        }

任何幫助將不勝感激。 我正在使用Visual Studio2015。我的整個配置文件如下

     <?xml version="1.0" encoding="utf-8"?>

Answer 1

嘗試將其添加到<configuration>節點中的<configuration> ：

<dataConfiguration defaultDatabase="Dbconnection" />
