Question

Hi,

I want to replace

margin:100px 100px 100px 100px;

with

paragraphSpaceBefore: 100px;
paragraphEndIndent: 100px;
paragraphSpaceAfter: 100px;
paragraphStartIndent: 100px;

How can i achieve this in C#?

Well, in that particular case, you can simply do: output = input.Replace("px", ""); Similarly, in the 'margins' example, you can simply replace this line: string[] items = margins[i].Split(':')[1].Trim(';').Split(' '); with this one: string[] items = margins[i].Split(':')[1].Trim(';') .Replace("px", "") .Split(' '); More generally, you can get rid of the units using regular expressions: string input = "font-size:0.2px"; string size = @":(\d+(\.\d+)?)(px|%|em|pt)\s*"; string rep =":$1"; string output = Regex.Replace(input, size, rep);

Thanks both of you. I have one more query ., how can i remove the unit from the string"font-size:0.2px" so i need to replace "font-size:0.2px" with "font-size:0.2" Can it be the following: string fntSize = @"font-size:[(\d+)(px|%|em|pt)\s*]+"; string rep ="font-size:$1"; output= Regex.Replace(input, fntSize, rep));

In that case, I think it's too complicated to use regular expressions and I'd use a variation of Jignesh's approach instead: using System; class Test { static void Main() { string[] margins = { "margin:25px 50px 75px 100px;", "margin:25px 50px 75px;", "margin:25px 50px;", "margin:25px;" }; string[] paras = { "paragraphSpaceBefore: ", "paragraphEndIndent: ", "paragraphSpaceAfter: ", "paragraphStartIndent: " }; for(int i = 0; i { string[] items = margins[i].Split(':')[1].Trim(';').Split(' '); switch(items.Length) { case 1: margins[i] = String.Format("{0}{4};
{1}{4};
{2}{4};
{3}{4};", paras[0], paras[1], paras[2], paras[3], items[0]); break; case 2: margins[i] = String.Format("{0}{2};
{1}{3};", paras[0], paras[1], items[0], items[1]); break; case 3: margins[i] = String.Format("{0}{3};
{1}{4};
{2}{5};", paras[0], paras[1], paras[2], items[0], items[1], items[2]); break; case 4: margins[i] = String.Format("{0}{4};
{1}{5};
{2}{6};
{3}{7};", paras[0], paras[1], paras[2], paras[3], items[0], items[1], items[2], items[3]); break; default: break; } } // check it works for all cases foreach(string margin in margins) Console.WriteLine("{0}
", margin); Console.ReadKey(); } } The output should be: paragraphSpaceBefore: 25px; paragraphEndIndent: 50px; paragraphSpaceAfter: 75px; paragraphStartIndent: 100px; paragraphSpaceBefore: 25px; paragraphEndIndent: 50px; paragraphSpaceAfter: 75px; paragraphSpaceBefore: 25px; paragraphEndIndent: 50px; paragraphSpaceBefore: 25px; paragraphEndIndent: 25px; paragraphSpaceAfter: 25px; paragraphStartIndent: 25px;

Thank you Vulpes :-) But There can be 4 scenario: 1) margin:25px 50px 75px 100px; //Should be converted to paragraphSpaceBefore: 25px; paragraphEndIndent: 50px; paragraphSpaceAfter: 75px; paragraphStartIndent: 100px; 2) margin:25px 50px 75px; //Should be converted to paragraphSpaceBefore: 25px; paragraphEndIndent: 50px; paragraphSpaceAfter: 75px; 3) margin:25px 50px; //Should be converted to paragraphSpaceBefore: 25px; paragraphEndIndent: 50px; 4) margin:25px; //Should be converted to paragraphSpaceBefore: 25px; paragraphEndIndent: 25px; paragraphSpaceAfter: 25px; paragraphStartIndent: 25px;

hi, try... var margin = "margin:100px 100px 100px 100px;"; var marginsplit = margin.Split(new char[] { ':' }); var valueSpilt = marginsplit[1].Split(new char[] { ' ' }); var newSting = "paragraphSpaceBefore: " + valueSpilt[0] + "; "; newSting += "paragraphEndIndent: " + valueSpilt[1] + "; "; newSting += "paragraphSpaceAfter: " + valueSpilt[2] + "; "; newSting += "paragraphStartIndent: " + valueSpilt[3] ; hope this will help you.

Using regular expressions, try this: string text = "margin:100px 100px 100px 100px;"; // say string original = @"margin:(\d+)px (\d+)px (\d+)px (\d+)px;"; string replacement = "paragraphSpaceBefore: $1px;
" + "paragraphEndIndent: $2px;
" + "paragraphSpaceAfter: $3px;
" + "paragraphStartIndent: $4px;"; text = Regex.Replace(text, original, replacement);
