Question

I made a program in which I want to copy a file from one folder to another. But I want to name that file from textbox. I am using below code. Please help me

FileInfo receipt = new FileInfo(@"C:\ssds\Receipt.xml");
receipt.CopyTo(@"C:\");
MessageBox.Show("XML Is created");

In receipt.CopyTo I need to write the name from the text box.

Answer 1

If it’s just adding a filename then use string.Format

receipt.CopyTo(string.Format(@"C:\{0}",textBox1.Text));

or stringConcat

receipt.CopyTo(string.Concat(@"C:\",textBox1.Text));

if it may contain parts of paths or absolute paths (in the case you use some SaveFileDialog), then Darin’s answer using Path class is what you need
