c# - 将参数化查询发送到数据库的更简单方法？

Question

有没有办法用更少的行编写以下代码？执行这样一个简单的查询似乎需要很多代码。没有 LINQ，因为我使用的是 VS2005。VB 或 C# 中的答案都是可以接受的。

Using cmd As DbCommand = oDB.CreateCommand()
    cmd.CommandText = "SELECT * FROM [Table1] WHERE [Date] BETWEEN @Date1 AND @Date2"
    cmd.CommandTimeout = 30
    cmd.CommandType = CommandType.Text
    cmd.Connection = oDB
    Dim param As DbParameter
    param = cmd.CreateParameter()
    param.Direction = ParameterDirection.Input
    param.DbType = DbType.Date
    param.ParameterName = "@Date1"
    param.Value = Now().Date
    cmd.Parameters.Add(param)
    param = cmd.CreateParameter()
    param.Direction = ParameterDirection.Input
    param.DbType = DbType.Date
    param.ParameterName = "@Date2"
    param.Value = Now().Date.AddDays(intDaysAhead)
    cmd.Parameters.Add(param)
End Using
Dim reader As DbDataReader = cmd.ExecuteReader()

Answer 1

这些可能是您可以获得的最少行数：

Using con = New SqlConnection("Connectionstring")
    Using cmd = New SqlCommand("SELECT * FROM [Table1] WHERE [Date] BETWEEN @Date1 AND @Date2", con)
        cmd.CommandTimeout = 30
        cmd.Parameters.AddWithValue("@Date1", Date.Today)
        cmd.Parameters.AddWithValue("@Date2", Date.Today.AddDays(intDaysAhead))
        con.Open()
        Using reader = cmd.ExecuteReader()

        End Using
    End Using
End Using

（假设SqlClient但其他数据提供者类似）
