This is a pretty straightforward task:

VB

Dim text = "Line 1" + vbCrLf +
           "Line 2" + vbCrLf +
           "Line 3" + vbCrLf +
           "Line 4" + vbCrLf +
           "Line 5" + vbCrLf

Dim lines = text.Split(New Char() {vbCr, vbLf}, StringSplitOptions.RemoveEmptyEntries)

text = String.Join(vbCrLf + "- ", lines) + vbCrLf

Solution 1

Don't use foreach for this. Use a normal for loop and start the index at 1 instead of 0.

The TextBox does not know the concept of "line" so you have to parse the text, probably .Split on Environment.NewLine, the go through the resulting string array and just not modify the first item in the array.
