Regular Expression for string formation

Question

Hello All This is sampath i have one query for string formation from the strings provided.I was thinking whether this can be achieved through regular expression. Kindly help me in this regard. string str1 = Declare Local variable   of type   and initialize with   ; string str2 = Declare Local variable b_test of type bool and initialize with 10; Need to extract the values to same word in str2. When i pass two aruguments for a function and function should return the output has below mentioned: bool b_test =10; kindly help me in this regard... Thanks Sampath

Incidentally although you asked for this to be done using regular expressions you can do it more easily using String.Split: using System; class Test { static void Main() { string str1 = Declare Local variable \ \ of type \ \ and initialize with \ \ ; string str2 = Declare Local variable b_test of type bool and initialize with 10; string decl = CreateDeclaration(str1 str2); Console.WriteLine(decl); Console.ReadKey(); } static string CreateDeclaration(string str1 string str2) { string[] words1 = str1.Split(' '); string[] words2 = str2.Split(' '); string var =  datatype =  value = ; for(int i = 0; i { if (words1[i] == \ \) var = words2[i]; else if (words1[i] == \ \) datatype = words2[i]; else if (words1[i] == \ \) value = words2[i]; } return String.Format({0} {1} = {2}; datatype var value); } }

Try this: using System; using System.Text.RegularExpressions; class Test { static void Main() { string str1 = Declare Local variable \ \ of type \ \ and initialize with \ \ ; string str2 = Declare Local variable b_test of type bool and initialize with 10; string decl = CreateDeclaration(str1 str2); Console.WriteLine(decl); Console.ReadKey(); } static string CreateDeclaration(string str1 string str2) { string regExp1 = @( )?; MatchCollection mc1 = Regex.Matches(str1 regExp1); string regExp2 = @\b\w+\b; MatchCollection mc2 = Regex.Matches(str2 regExp2); string var =  datatype =  value = ; for(int i = 0; i { if (mc1[i].Value == \ \) var = mc2[i].Value; else if (mc1[i].Value == \ \) datatype = mc2[i].Value; else if (mc1[i].Value == \ \) value = mc2[i].Value; } return String.Format({0} {1} = {2}; datatype var value); } }
