如何通过Massive建立与数据库的连接?

Massive中有一个方法用于打开连接,但它接受连接字符串的名称。我想给它连接字符串。我怎么能这样做?

答案 0 :(得分:2)

在Open()方法的Massive代码中创建了DynamicModel,在DynamicModel构造函数中我发现了这一行(Massive.cs 127行):

ConnectionString = ConfigurationManager.ConnectionStrings[connectionStringName].ConnectionString;

这意味着您需要在配置文件中存储连接字符串并传递给Open方法适当的连接字符串名称。

您需要创建重载方法来接受连接字符串。这是一个例子:

public static DynamicModel Open(string connectionString, string providerName="System.Data.SqlClient") 
{
        dynamic dm = new DynamicModel(connectionString, providerName);
        return dm;
}

public DynamicModel(string connectionString, string providerName ="System.Data.SqlClient", string tableName = "", 
     string primaryKeyField = "", string descriptorField = "") 
{
        TableName = tableName == "" ? this.GetType().Name : tableName;
        PrimaryKeyField = string.IsNullOrEmpty(primaryKeyField) ? "ID" : primaryKeyField;
        DescriptorField = descriptorField;

        _factory = DbProviderFactories.GetFactory(providerName);
        ConnectionString = connectionString;
}
