C# 如何将参数传递给ms access以恢复数据

我是ms access新手。有人能帮我发送参数到查询并获取数据吗（举个例子）…我正在使用C作为编码语言（Asp.Net）

提前感谢

您需要以下使用声明：

using System.Data.OleDb;

例如：

string ConnString = "Microsoft.Jet.OleDb.4.0;Data Source=|DataDirectory|Northwind.mdb";
string SqlString = @"Select * From Contacts 
                    Where FirstName = @FirstName And LastName = @LastName";
using (OleDbConnection conn = new OleDbConnection(ConnString))
{
    using (OleDbCommand cmd = new OleDbCommand(SqlString, conn))
    {
        cmd.CommandType = CommandType.Text;
        cmd.Parameters.AddWithValue("FirstName", txtFirstName.Text);
        cmd.Parameters.AddWithValue("LastName", txtLastName.Text);
        conn.Open();
        using (OleDbDataReader reader = cmd.ExecuteReader())
        {
            while (reader.Read())
            {
                Response.Write(reader["FirstName"].ToString() + " " + reader["LastName"].ToString());
            }
        }
    }
}

您将需要以下using语句：

using System.Data.OleDb;

例如：

string ConnString = "Microsoft.Jet.OleDb.4.0;Data Source=|DataDirectory|Northwind.mdb";
string SqlString = @"Select * From Contacts 
                    Where FirstName = @FirstName And LastName = @LastName";
using (OleDbConnection conn = new OleDbConnection(ConnString))
{
    using (OleDbCommand cmd = new OleDbCommand(SqlString, conn))
    {
        cmd.CommandType = CommandType.Text;
        cmd.Parameters.AddWithValue("FirstName", txtFirstName.Text);
        cmd.Parameters.AddWithValue("LastName", txtLastName.Text);
        conn.Open();
        using (OleDbDataReader reader = cmd.ExecuteReader())
        {
            while (reader.Read())
            {
                Response.Write(reader["FirstName"].ToString() + " " + reader["LastName"].ToString());
            }
        }
    }
}

ASP.NET提供了一个控件，大大简化了这一过程。您可以像下面的示例一样使用它，并将结果直接绑定到gridview

<asp:AccessDataSource
  id="InvoiceAccessDataSource"
  DataFile="~/App_Data/Northwind.mdb"
  runat="server"
  SelectCommand="[Employee Sales By Country]"
  SelectCommandType="StoredProcedure">
  <SelectParameters>
    <asp:Parameter Name="Beginning Date" Type="DateTime" defaultValue="1/1/1997" />
    <asp:Parameter Name="Ending Date" Type="DateTime" defaultValue="1/31/1997" />
  </SelectParameters>
</asp:AccessDataSource>

<asp:GridView
  id="InvoiceGridView"
  runat="server"
  AutoGenerateColumns="True"
  DataSourceid="InvoiceAccessDataSource" />

请输入代码？显示一些您已经编写的代码？从ms重新标记为ms access。标记ms很少使用且不一致。请输入代码？显示一些您已经编写的代码？从ms重新标记为ms access。标记ms很少使用，而且不一致。
