这是我连接sql数据库的部分代码：
private void Form1_Load(object sender, System.EventArgs e)
{
string source="server=127.0.0.1;"+"uid=sa;pwd=sa;"+"database=DatabaseName";
string select ="select * from TableName";
SqlConnection conn = new SqlConnection(source);
SqlDataAdapter da= new SqlDataAdapter(select,conn);
DataSet ds= new DataSet();
da.Fill(ds,"TableName");
dataGrid1.SetDataBinding(ds,"TableName");
}
应该还可以优化的,却不知道怎么优化，望指教。
string strConn= "Provider=Microsoft.Jet.OLEDB.4.0;"+"Password=;User ID=Admin;"+"data source=\\192.168.0.22"+"inital catalog=student.mdb";
//string strConn="Provider = Microsoft.Jet.OLEDB.4.0; Data Source=192.168.0.22";
OleDbConnection myConn=new OleDbConnection(strConn);
myConn.Open();
string strInsert="INSERT INTO uuser(uuser,password,userid) VALUES(";
strInsert+=textBox1.Text+",'";
strInsert+=textBox2.Text+"''";
strInsert+=textBox3.Text+")";
OleDbCommand inst=new OleDbCommand(strInsert,myConn);
inst.ExecuteNonQuery();
myConn.Close();
连接access的。
