Getting the text from a RichTextBox

private void SaveFile()
{
Stream myStream;
SaveFileDialog saveFileDialog1 = new SaveFileDialog();
saveFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*";
saveFileDialog1.FilterIndex = 2;
saveFileDialog1.RestoreDirectory = true;
if (saveFileDialog1.ShowDialog() == DialogResult.OK)
{
if ((myStream = saveFileDialog1.OpenFile()) != null)
{
rtb1.Text().get();
}
}
}
I use this when trying to get the text of a richtextbox and save it but it always comes up with error, CS1955

If you just want to write a simple text file then you can use the File.WriteAllText command instead.
if (saveFileDialog1.ShowDialog() == DialogResult.OK)
{
File.WriteAllText(saveFileDialog1.Filename, rtb1.Text);
}
You just need to specify the filename with path, and then the text, which in this case is rtb1.Text (no brackets!)

C# Multiline textBox to .TXT file

I'm definitely using the wrong method. Actually I'm trying to convert from JAVA to C# and it's beginning to become tough ..
Anyway, I have a textBox1 that is multiline, I write to it by for looping an ArrayList.
The textbox1 looks like this:
Website: https://google.dk
Firmanavn: Google LLC
Email: google#gmail.com
CVR: 123456
gScore: 1
gLink: googlePageSpeedLink
The code that I use right now, which manages to create a file, but it ends up empty. I am surely doing something wrong, and I'm unsure how to write the textBox to the file.
private void button3_Click(object sender, EventArgs e)
{
Stream myStream;
SaveFileDialog saveFileDialog1 = new SaveFileDialog();
saveFileDialog1.Filter = "txt files (*.txt)|";
saveFileDialog1.FilterIndex = 2;
saveFileDialog1.RestoreDirectory = true;
if (saveFileDialog1.ShowDialog() == DialogResult.OK)
{
String path = Path.GetFullPath(saveFileDialog1.FileName);
path = DialogResult.ToString();
if ((myStream = saveFileDialog1.OpenFile()) != null)
{
File.WriteAllText(path, textBox1.Text);
myStream.Close();
}
}
}
Any help appreciated... :3 :3 I searched for around 1½ hours on StackOverFlow but I didn't manage to see a sample that would match my way of code :3
I hope it's not a duplicate question, thanks a lot for your answers :)

You don't need the Stream:
SaveFileDialog saveFileDialog1 = new SaveFileDialog();
saveFileDialog1.Filter = "txt files (*.txt)|";
saveFileDialog1.FilterIndex = 2;
saveFileDialog1.RestoreDirectory = true;
if (saveFileDialog1.ShowDialog() == DialogResult.OK)
{
string path = Path.GetFullPath(saveFileDialog1.FileName);
File.WriteAllText(path, textBox1.Text);
}

How could I make this set of code save the user input into another folder?

I am so lost.... how could I make this set of code save the user input into another folder? (Im trying to save .png files if you need to know that)
private void button1_Click(object sender, System.EventArgs e)
{
Stream myStream ;
SaveFileDialog saveFileDialog1 = new SaveFileDialog();
saveFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*" ;
saveFileDialog1.FilterIndex = 2 ;
saveFileDialog1.RestoreDirectory = true ;
if(saveFileDialog1.ShowDialog() == DialogResult.OK)
{
if((myStream = saveFileDialog1.OpenFile()) != null)
{
myStream.Close();
}
}
}

There is also some other and or additional code that you would really need to write for example if the user selects a file from one folder, then you could just capture that FilePath using System.IO and look up how to use GetFilePath , FileName, etc... then once the file is selected that they want to save ..why not use the File.Copy() method. there are plenty of additional examples online here on SO as well
if (saveFileDialog1.ShowDialog() == DialogResult.OK)
{
using( Stream myStream = File.Open(saveFileDialog1.FileName, FileMode.CreateNew))
using( StreamWriter sw = new TextWriter(myStream) )
{
sw.Write("here you can write lines from a file that you read or you can simple write what ever text you are wanting to save to a file this should help you get started" );
}
}
Here is an even simpler way of doing it
if (saveFileDialog1.ShowDialog() == DialogResult.OK)
{
System.IO.File.Copy(saveFileDialog1.Filename, "some dest filePath");
}

SaveFileDialog saves as blank ext? - C#

So I got the hang of doing OpenFileDialog, now I can't seem to understand SaveFileDialog. Looked at a few pages and each of them have there own ways of doing it, but none of them get down to the point of saving the text that is in the richtextbox to a file.
private void button1_Click(object sender, EventArgs e)
{
Stream myStream;
SaveFileDialog exportdialogue = new SaveFileDialog();
exportdialogue.Filter = "txt files (*.txt)|*.txt*";
exportdialogue.FilterIndex = 2;
exportdialogue.RestoreDirectory = true;
if (exportdialogue.ShowDialog() == DialogResult.OK)
{
if ((myStream = exportdialogue.OpenFile()) != null)
{
StreamWriter wText = new StreamWriter(myStream);
wText.Write("Some Text");
myStream.Close();
}
}
}
Using a richtextbox, and a normal button, also "using System.IO;" (For the Stream )
I am trying to get the button to use SaveFileDialog so it can export the content within the richtextbox to a text file.
Issue:
Unsure what I need to do from here to make it save contents from the rich text box.
Don't know why SaveFileDialog saves files with no extension when a filter is in place.

You set:
exportdialogue.Filter = "txt files (*.txt)|*.txt*";
which only contains ONE filter, but you set:
exportdialogue.FilterIndex = 2;
which means to use the SECOND filter. (FilterIndex is 1-based).
If you set FilterIndex = 1, your file should have the extension .txt

you can use using {} block to solve the issue:
Try this:
SaveFileDialog exportdialogue = new SaveFileDialog();
exportdialogue.Filter = "txt files (*.txt)|*.txt*";
exportdialogue.FilterIndex = 2;
exportdialogue.RestoreDirectory = true;
if (exportdialogue.ShowDialog() == DialogResult.OK)
{
using( Stream myStream = exportdialogue.OpenFile())
{
StreamWriter wText = new StreamWriter(myStream);
wText.Write("Some Text");
wText.Close();
}
}

you need to use savefile method of reach textbox and pass to it the filename from savedialogbox.
reachtextbox.SaveFile(exportdialogue.FileName);
ps: it will be something like above code.

Winforms Save as

Does anyone know any articles or sites showing how to create a "Save as" dialogue box in win forms. I have a button, user clicks and serializes some data, the user than specifies where they want it saved using this Save as box.

You mean like SaveFileDialog?
From the MSDN sample, slightly amended:
using (SaveFileDialog dialog = new SaveFileDialog())
{
dialog.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*" ;
dialog.FilterIndex = 2 ;
dialog.RestoreDirectory = true ;
if (dialog.ShowDialog() == DialogResult.OK)
{
// Can use dialog.FileName
using (Stream stream = dialog.OpenFile())
{
// Save data
}
}
}

Use the SaveFileDialog control/class.

Im doing a notepad application in c# i came over this scenario to save file as try this out.It will work perfectly
private void saveAsToolStripMenuItem_Click(object sender, EventArgs e)
{
SaveFileDialog saveFileDialog1 = new SaveFileDialog();
saveFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*";
saveFileDialog1.FilterIndex = 2;
saveFileDialog1.RestoreDirectory = true;
if (saveFileDialog1.ShowDialog() == DialogResult.OK)
{
System.IO.StreamWriter file = new System.IO.StreamWriter(saveFileDialog1.FileName.ToString());
file.WriteLine(richTextBox1.Text);
file.Close();
}
}
