net5中如何通过AddScoped分别注入两个SqlSugarClient使用无法使用命名空间的方式

可以使用自定义的工厂方法来分别注入两个SqlSugarClient。

首先，创建一个自定义的工厂类：

public class SqlSugarClientFactory
{
    private readonly IConfiguration _configuration;

    public SqlSugarClientFactory(IConfiguration configuration)
    {
        _configuration = configuration;
    }

    public SqlSugarClient CreateClient1()
    {
        var connection = _configuration.GetConnectionString("Connection1");
        return new SqlSugarClient(new ConnectionConfig()
        {
            ConnectionString = connection,
            DbType = DbType.SqlServer,
            IsAutoCloseConnection = true,
            InitKeyType = InitKeyType.Attribute
        });
    }

    public SqlSugarClient CreateClient2()
    {
        var connection = _configuration.GetConnectionString("Connection2");
        return new SqlSugarClient(new ConnectionConfig()
        {
            ConnectionString = connection,
            DbType = DbType.SqlServer,
            IsAutoCloseConnection = true,
            InitKeyType = InitKeyType.Attribute
        });
    }
}

在Startup.cs中进行注册：

services.AddScoped<SqlSugarClientFactory>();

services.AddScoped<SqlSugarClient>(serviceProvider =>
{
    var factory = serviceProvider.GetService<SqlSugarClientFactory>();
    return factory.CreateClient1();
});

services.AddScoped<SqlSugarClient>(serviceProvider =>
{
    var factory = serviceProvider.GetService<SqlSugarClientFactory>();
    return factory.CreateClient2();
});

在需要使用SqlSugarClient的类中，可以使用构造函数注入方式进行注入：

public class MyClass
{
    private readonly SqlSugarClient _client1;
    private readonly SqlSugarClient _client2;

    public MyClass(SqlSugarClient client1, SqlSugarClient client2)
    {
        _client1 = client1;
        _client2 = client2;
    }

    public void Method1()
    {
        // 使用_client1操作数据库
    }

    public void Method2()
    {
        // 使用_client2操作数据库
    }
}
