谁能帮我解释一下下面这个东西的方法都是干什么用的啊？？
namespace CNTD.Center.Data
{
public abstract class DataObj
{
protected SqlConnection sqlConn;

public DataObj(string newConnStr);

protected string ConnStr { get; }

protected int RunProcedure(string storeProcName, IDataParameter[] parames);
protected int RunProcedure(string storeProcName, IDataParameter[] parames, out int rowsAffected);
protected DataSet RunProcedure(string storeProcName, IDataParameter[] parames, string tableName);
protected void RunProcedure(string storeProcName, IDataParameter[] parames, DataSet dataSet, string tableName);
protected SqlDataReader RunProcedureReader(string storeProcName, IDataParameter[] parames);
protected DataTable RunProcedureTable(string storeProcName, IDataParameter[] parames);
protected DataTable RunProcedureTable(string storeProcName, IDataParameter[] parames, string tableName);
protected SqlParameter SetParaInt(string datebase);
protected SqlParameter SetParaStr(string datebase);
protected SqlParameter[] SetParaZu(int id);
protected SqlParameter[] SetParaZu(string id);
protected SqlParameter[] SetParaZu(int iv, int iv2);
protected SqlParameter[] SetParaZu(int iv, string sv);
protected SqlParameter[] SetParaZu(string iv, string iv2);
}
}
[解决办法]
自己写的一个操作数据库的类吧？
