Question

我将vb代码中的前一个经典asp转换为c＃中的asp.net。我无法为记录集存储过程变量（objRs）分配变量。我试过把它设置为 strap = objRs("strap"); 但这给了我一个错误的objRS＆＃34;局部变量ADODB.Recordset objRS - 方法代表或事件是预期的＆＃34;

我用括号尝试过： strap = objRs["strap"]; 这给了我第二个带＃34;不明确的索引器：ADODB.Fields字段（在interface_Recordset中）的错误; ADODB.Fields字段（在interface_Recordset15中）; ＆＃34;＆＃34; （在interface_Recordset20中）; ＆＃34;＆＃34; （在interface_Recordset21中）;匹配＆＃34;

我也尝试了各种Convert.ToString方法，但没有成功。

更新7/31/17：

我接受了Alex和Chetan的建议并重新编写了代码，只使用ADO.Net和SQL Connections和Commands。我现在可以使用SqlDataReader将变量分配给前一个记录集objRs存储过程变量（现在是一个SqlCommand）。

c＃声明记录集变量等于存储过程中的字符串
