找不到.NET

来源：百度知道 编辑：UC知道 时间：2024/05/29 11:09:46
string dataProviderName = BalloonShopConfiguration.DbProviderName;
string connectionString = BalloonShopConfiguration.DbConnectionString;
DbProviderFactory factory = DbProviderFactories.GetFactory(dataProviderName);
DbConnection conn = factory.CreateConnection();
conn.ConnectionString = connectionString;
DbCommand comm=conn.CreateCommand();
comm.CommandType = CommandType.StoredProcedure;
return comm;
-----------------------------------------------------------------
DbProviderFactory factory = DbProviderFactories.GetFactory(dataProviderName)；这句有错。
找不到请求的 .Net Framework 数据提供程序。可能没有安装。
该怎么解决。请各位帮忙！
