如何在数据网格视图中从MS Access查看数据

本文关键字：数据 MS Access 视图 数据网 网格 | 更新日期: 2023-09-27 18:08:19

我是C-Sharp的新手，我正试图从C-Sharp访问我的数据库，我编写了以下代码，我不知道在视图数据旁边写什么。我在网上搜索了这个，但没有得到很多。请告诉我这个简单的代码。

string connection = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=F:'Database3.accdb";
OleDbConnection conn = new OleDbConnection(connection);
conn.Open();
OleDbCommand cmd = new OleDbCommand("Select * from score", conn);
OleDbDataAdapter da = new OleDbDataAdapter(cmd);
da.SelectCommand = cmd;

如何在数据网格视图中从MS Access查看数据

参考代码: 

string strProvider = "@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=F:'Database3.accdb";
string strSql = "Select * from score";
OleDbConnection con = new OleDbConnection(strProvider);
OleDbCommand cmd = new OleDbCommand(strSql, con);
con.Open();
cmd.CommandType = CommandType.Text;
OleDbDataAdapter da = new OleDbDataAdapter(cmd);
DataTable scores = new DataTable();
da.Fill(scores);
dataGridView1.DataSource = scores;

试试这个

        try
        {
        Dataset myDataSet=new Dataset();
        string connection = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=F:'Database3.accdb";
        OleDbCommand cmd = new OleDbCommand("Select * from score", conn);
        OleDbDataAdapter myDataAdapter = new OleDbDataAdapter(cmd );
        connection .Open();
        myDataAdapter.Fill(myDataSet,"TableName");
        }
        catch (Exception ex)
        {
              Console.WriteLine("Error: Failed to retrieve the required data from the DataBase.'n{0}", ex.Message);
              return;
        }
        finally
        {
              connection .Close();
        }

记住，良好的编码实践，始终连接应该打开Try BlockFinally Block
