,可以通过以下步骤实现:
{
"ConnectionStrings": {
"DataSource1": "Server=server1;Database=db1;User Id=user1;Password=pass1;",
"DataSource2": "Server=server2;Database=db2;User Id=user2;Password=pass2;"
}
}
using Microsoft.Extensions.Configuration;
using System.Data.SqlClient;
public class DataAccessLayer
{
private readonly IConfiguration _configuration;
public DataAccessLayer(IConfiguration configuration)
{
_configuration = configuration;
}
public void ConnectToDataSources()
{
string dataSource1ConnectionString = _configuration.GetConnectionString("DataSource1");
string dataSource2ConnectionString = _configuration.GetConnectionString("DataSource2");
using (SqlConnection connection1 = new SqlConnection(dataSource1ConnectionString))
{
// Connect to DataSource1 and perform database operations
}
using (SqlConnection connection2 = new SqlConnection(dataSource2ConnectionString))
{
// Connect to DataSource2 and perform database operations
}
}
}
public class BusinessLogicLayer
{
private readonly DataAccessLayer _dataAccessLayer;
public BusinessLogicLayer(DataAccessLayer dataAccessLayer)
{
_dataAccessLayer = dataAccessLayer;
}
public void ConnectToDataSources()
{
_dataAccessLayer.ConnectToDataSources();
}
}
通过以上步骤,你可以在ASP.NET核心应用程序中连接两个数据源,并且可以根据具体的业务需求执行相应的数据库操作。请注意,以上示例中的代码仅为演示目的,实际应用中可能需要根据具体情况进行适当的修改和优化。
