Replace a string in text file with a 2D array

Question

Dear friends I have 2D array of doubles in C# and also I have a text file including many texts. Somewhere in the text file I have a text called[$CHANGE]. I would like to replace [$CHANGE] with the content of the 2D array with the same number of columns and rows. How can I do this in a short way? For example. 1. My original text file C:/MyText.txt: HELLO TO EVERY ONE [$CHANGE] NOW GOODBYE 2. My Array: 1 2 3 1.1 2.1 3.1 5.1 5.2 5.3 3. My text file after replacing the array: HELLO TO EVERY ONE 1 2 3 1.1 2.1 3.1 5.1 5.2 5.3 NOW GOODBYE

Hi Try this code - double[] array = new double[] { {1 23} {1.1 2.13.1} {5.1 5.25.3} }; int len = array.GetLength(0); int len1 = array.GetLength(1); string str = ; for (int i = 0; i { for (int j = 0; j { str += array[i j] +  ; } str += 
; } string text = File.ReadAllText(Server.MapPath(Text.txt)); text = text.Replace([\$CHANGE\] str.TrimEnd('
')); File.WriteAllText(Server.MapPath(Text.txt) text);
