Question

    string connection = "Provider=Microsoft.ACE.OLEDB.12.0 ;" + "Data Source=D:\\it101\\LoginForm\\App_Data\\registration.mdb";

    string query = "INSERT INTO registration values (adsdsa,adsadsa,87987,dasdsa)";
    OleDbConnection con = new OleDbConnection(connection);
    OleDbCommand cmd = new OleDbCommand();
    cmd.CommandText = query;
    cmd.CommandType = CommandType.Text;
    cmd.Connection = con;
    con.Open();

    OleDbDataAdapter da = new OleDbDataAdapter(query,con);

    DataSet ds =new DataSet();


    da.Fill(ds);
    GridView1.DataSource = ds;
    GridView1.DataBind();
    con.Close();

Answer 1

用于插入

string queryString = "INSERT INTO registration values ('adsdsa','adsadsa',87987,'dasdsa')";
using (OleDbConnection connection = new OleDbConnection(connection))
using (OleDbCommand command = new OleDbCommand(queryString, connection))
    {
        connection.Open();
        command.ExecuteNonQuery();
    }

加载数据时

using(OleDbConnection con = new OleDbConnection(connection))
using(var adapter = new OleDbDataAdapter("select * from registration", con)
{
  DataSet ds =new DataSet();
  adapter.Fill(ds);
  GridView1.DataSource = ds;
  GridView1.DataBind();
}

Answer 2

你需要引用你的字符串值 -

 string query = "INSERT INTO registration values ('adsdsa','adsadsa',87987,'dasdsa')";

Answer 3

使用此

更改插入行

string query = "INSERT INTO registration values ('adsdsa','adsadsa',87987,'dasdsa')";

Answer 4

连接后打开（）;

添加此内容 cmd.open（）; cmd.ExecuteNonQuery（）;

表示将数据传递给值时添加这样的引号插入表名值（'data1'，'data2'）我希望这能帮到您。

Answer 5

请你试试这个：

string query = "INSERT INTO registration values ('adsdsa','adsadsa',87987,'dasdsa');

希望这会有所帮助..

使用oledb连接插入c＃查询不起作用
