如何在C#Windows窗体中同时获取动态numericupdown和文本框值 [英] How to get both dynamic numericupdown and textbox values in c# windows forms
问题描述
我有一个代码,其中TextBox和NumericUpDown工具是通过foreach循环动态生成的.现在,我希望能够获得两个值,在每次迭代中,这两个值都将被添加到数据库的同一行中.我有用于获取NumericUpDown值的代码,我想知道如何也可以实现获取TextBox值.
I have a code where TextBox and NumericUpDown tools are generated dynamically through a foreach loop. Now, I want to be able to get both values in which with each iteration, both their values would be added to the same row in the database. I have the code for getting the NumericUpDown values and I was wondering how can I implement getting the TextBox values too.
用于生成动态NumericUpDown和TextBox的代码
Code for generating the dynamic NumericUpDown and TextBox
t = temp.Split(';'); // e.g. t = Arial;32
int pointX = 70;
int pointY = 80;
int pointA = 300;
int pointB = 80;
for (int i = 0; i < N; i++)
{
foreach (object o in t)
{
TextBox a = new TextBox();
a.Text = o.ToString();
a.Location = new Point(pointX, pointY);
a.Size = new System.Drawing.Size(150, 25);
panel.Controls.Add(a);
panel.Show();
pointY += 30;
NumericUpDown note = new NumericUpDown();
note.Name = "Note" + i.ToString();
note.Location = new Point(pointA, pointB);
note.Size = new System.Drawing.Size(40, 25);
note.Maximum = new decimal(new int[] { 10, 0, 0, 0 });
panel.Controls.Add(note);
pointB += 30;
}
}
在单击按钮时获取动态NumericUpDown值的代码(数据库代码有效)
Code for getting dynamic NumericUpDown values on button click (the database code works)
foreach (NumericUpDown ctlNumeric in panel.Controls.OfType<NumericUpDown>())
{
var value = ctlNumeric.Value;
int number = Decimal.ToInt32(value);
sample_save = "INSERT INTO forthesis (testVal) VALUES ('" + number + "');";
MySqlConnection myConn = new MySqlConnection(connectionString);
MySqlCommand myCommand = new MySqlCommand(sample_save, myConn);
MySqlDataAdapter da = new MySqlDataAdapter(myCommand);
MySqlDataReader myReader;
myConn.Open();
myReader = myCommand.ExecuteReader();
myConn.Close();
MessageBox.Show(number.ToString());
}
样本输出,每行将插入数据库中
Sample output, each row would be inserted in the database
我如何也可以在TextBox中获取值?您的帮助将不胜感激.非常感谢!!!
How can I get the values in the TextBox(es) too? Your help will be much appreciated. Thank you so much!!!
推荐答案
也许您可以使用字符串-TextBox字典来保存匹配的配对文本框,如下所示:
Maybe you could use a string - TextBox dictionary to save the matching paired text box like this :
Dictionary<string, TextBox> textboxes = new Dictionary<string, TextBox>();
for (int i = 0; i < N; i++)
{
foreach (object o in t)
{
TextBox a = new TextBox();
.....
NumericUpDown note = new NumericUpDown();
note.Name = "Note" + i.ToString();
......
textboxes.Add(note.Name, a);
}
}
foreach (NumericUpDown ctlNumeric in panel.Controls.OfType<NumericUpDown>())
{
var value = ctlNumeric.Value;
int number = Decimal.ToInt32(value);
TextBox tb = textboxes[ctrlNumeric.Name];
String text = tb.Text;
.........
}
如果要删除文本框& NumericUpDowns-那么您也需要清除Dictionary-否则它将保留对它们的引用&垃圾收集器将不会清理它们.
If you are removing the TextBoxs & NumericUpDowns - then you will need to clear the Dictionary as well - otherwise it will retain references to them & they will not be cleaned up by the Garbage Collector.
