问题描述
我收到以下错误错误1'System.Data.SqlClient.SqlConnection'是'类型',但在下面的代码中使用像'变量',请帮助
string imgLoc = ; public Retrieve() { InitializeComponent(); } private void 浏览( object sender,RoutedEventArgs e) { SqlConnection cn = SqlConnection( global :: DatabaseApp.Properties。 Settings.Default.Database1ConnectionString); 尝试 { OpenFileDialog dlg = new 打开文件对话框(); dlg.Filter = JPG文件(* .jpg)| * .jpg | GIF文件(*。 gif)| * .gif |所有文件(*。*)| *。*; dlg.Title = 选择学生照片; if (dlg.ShowDialog()== System.Windows.Forms.DialogResult.OK) { imgLoc = dlg。 FileName.ToString(); picStud.ImageLocation = imgLoc; } } catch (Exception ex) { System.Windows.MessageBox.Show( ex.Message); } } private SqlConnection SqlConnection( string p) { throw new NotImplementedException(); }解决方案
你在<缺少 new 这个词pre> SqlConnection cn = SqlConnection(global :: DatabaseApp.Properties.Settings.Default.Database1ConnectionString);
ie
SqlConnection cn = new SqlConnection(global :: DatabaseApp.Properties.Settings.Default.Database1ConnectionString);
Am getting the following error "Error 1 'System.Data.SqlClient.SqlConnection' is a 'type' but is used like a 'variable'" in the below code kindly help
string imgLoc = ""; public Retrieve() { InitializeComponent(); } private void Browse(object sender, RoutedEventArgs e) { SqlConnection cn = SqlConnection(global::DatabaseApp.Properties.Settings.Default.Database1ConnectionString); try { OpenFileDialog dlg = new OpenFileDialog(); dlg.Filter = "JPG Files (*.jpg)|*.jpg|GIF Files (*.gif)|*.gif|All Files(*.*)|*.*"; dlg.Title = "Select Student Picture"; if (dlg.ShowDialog() == System.Windows.Forms.DialogResult.OK) { imgLoc = dlg.FileName.ToString(); picStud.ImageLocation = imgLoc; } } catch(Exception ex) { System.Windows.MessageBox.Show(ex.Message); } } private SqlConnection SqlConnection(string p) { throw new NotImplementedException(); } 解决方案 You are missing the word new in SqlConnection cn = SqlConnection(global::DatabaseApp.Properties.Settings.Default.Database1ConnectionString);i.e.
SqlConnection cn = new SqlConnection(global::DatabaseApp.Properties.Settings.Default.Database1ConnectionString);更多推荐
