how to make a reading operation with this writing textfile solution, please?
Textbox[]tbs = { textBox1, textBox2, textBox3, textBox4, textBox5 }; // add all of them in here
StringBuilder sb = new StringBuilder();
foreach(TextBox tb in tbs)
sb.AppendLine(tb.Text);
System.IO.File.WriteAllText(@"C:\myFile.txt", sb.ToString());
Jump to PostDo you mean a read of the file?
Try ReadAllText
Jump to PostStringBuilder AppenLine method appends a cr after every string of a textbox.
So you can use the string Split method to separate al the different textbox strings.Look it up in MSDN to find out how the Split method works.
Jump to PostThis is what I meant:
TextBox textBox1 = new TextBox(); TextBox textBox2 = new TextBox(); TextBox textBox3 = new TextBox(); TextBox textBox4 = new TextBox(); TextBox[] tbs = { textBox1, textBox2, textBox3, textBox4}; // suppose this string is read from a file string StrReadFromFile = "TB1text" + …
Yes, but how with readalltext. I have many textboxes. Look the précedent message it's ok for saving into the text file but i don't how to read text file to send into textbox1, textbox2, textbox3 etc...

Thanks ddanbe but i don't need the string split method i want just import variables of the myFile.txt(look my writing code of myFile.txt) to texboxes.
This is what I meant:
TextBox textBox1 = new TextBox();
TextBox textBox2 = new TextBox();
TextBox textBox3 = new TextBox();
TextBox textBox4 = new TextBox();
TextBox[] tbs = { textBox1, textBox2, textBox3, textBox4};
// suppose this string is read from a file
string StrReadFromFile = "TB1text" + "\n" + "TB2text" + "\n" + "TB3txt" + "\n" + "TB4txt" +"\n";
string[] tbxStrings = StrReadFromFile.Split(new char[]{'\n'});
//Drop the splitted tekst into the textboxes
for (int i = 0; i < tbs.Length; i++)
{
tbs[i].Text = tbxStrings[i];
}
Hope some code will make it clearer.
Another way to do this would be:
TextBox textBox1 = new TextBox();
TextBox textBox2 = new TextBox();
TextBox textBox3 = new TextBox();
TextBox textBox4 = new TextBox();
TextBox[] tbs = { textBox1, textBox2, textBox3, textBox4};
// suppose this string is read from a file
string StrReadFromFile = "TB1text" + "\n" + "TB2text" + "\n" + "TB3txt" + "\n" + "TB4txt" +"\n";
//Drop the splitted tekst into the textboxes
tbs[0].Text = (StrReadFromFile.Split('\n'))[0];
tbs[1].Text = (StrReadFromFile.Split('\n'))[1];
tbs[2].Text = (StrReadFromFile.Split('\n'))[2];
tbs[3].Text = (StrReadFromFile.Split('\n'))[3];
if(openFileDialog1.ShowDialog() ==System.Windows.Forms.DialogResult.OK)
{
TextBox textBox1 = new TextBox();
TextBox textBox2 = new TextBox();
TextBox textBox3 = new TextBox();
TextBox textBox4 = new TextBox();
TextBox[] tbs = { textBox1, textBox2, textBox3, textBox4};
// suppose this string is read from a file
string StrReadFromFile = "TB1text" + "\n" + "TB2text" + "\n" + "TB3txt" + "\n" + "TB4txt" +"\n";
string[] tbxStrings = StrReadFromFile.Split(new char[]{'\n'});
//Drop the splitted tekst into the textboxes
for (int i = 0; i < tbs.Length; i++)
{
tbs[i].Text = tbxStrings[i];
}
}
Sorry but it's not working for me. I think i forget something if you can help me please.
if(openFileDialog1.ShowDialog() ==System.Windows.Forms.DialogResult.OK)
{
TextBox TextBox1 = new TextBox();
TextBox TextBox2 = new TextBox();
TextBox TextBox3 = new TextBox();
TextBox TextBox4 = new TextBox();
TextBox[] tbs = { TextBox1, TextBox2, TextBox3, TextBox4};
// suppose this string is read from a file
string StrReadFromFile = "TB1text" + "\n" + "TB2text" + "\n" + "TB3txt" + "\n" + "TB4txt" +"\n";
string[] tbxStrings = StrReadFromFile.Split(new char[]{'\n'});
//Drop the splitted tekst into the textboxes
for (int i = 0; i < tbs.Length; i++)
{
tbs[i].Text = tbxStrings[i];
}
}
Could you please tell, WHAT is not working?
there's nothing in my textboxes.
The code I gave you was just a raw sketch of what it could look like.
It is up to you to fill in the details, size, font etc.
Here is (again minimal but working code)
TextBox TextBox1 = new TextBox();
TextBox TextBox2 = new TextBox(); TextBox2.Location = new Point(50, 50);
TextBox TextBox3 = new TextBox(); TextBox3.Location = new Point(50, 80);
TextBox TextBox4 = new TextBox(); TextBox4.Location = new Point(100, 100);
TextBox[] tbs = { TextBox1, TextBox2, TextBox3, TextBox4};
// suppose this string is read from a file
string StrReadFromFile = "TB1text" + "\n" + "TB2text" + "\n" + "TB3txt" + "\n" + "TB4txt" +"\n";
string[] tbxStrings = StrReadFromFile.Split(new char[]{'\n'});
//Drop the splitted tekst into the textboxes
for (int i = 0; i < tbs.Length; i++)
{
tbs[i].Text = tbxStrings[i];
}
//the form needs to know his controls
this.Controls.AddRange(tbs);
I have placed this code right after the initializeComponent call of the form constructor.
Ok, Thank's. I found another solution and it's better.
if(openFileDialog1.ShowDialog() ==System.Windows.Forms.DialogResult.OK)
{
StringBuilder loaded = new StringBuilder();
StreamReader reader = new StreamReader(openFileDialog1 .FileName );
String line;
// Read and display lines from the file until the end of
// the file is reached.
while ((line = reader.ReadLine()) != null)
{
String[] content = line.Split('#');
String name = content[0];
String value = content[1];
Control control = Controls[name];
if (control is TextBox)
(control as TextBox).Text = value;
else if (control is CheckBox)
(control as CheckBox).Checked = (value.Equals("true", StringComparison.OrdinalIgnoreCase));
}
}
