This question is not clear. What have you tried so far ? What do you mean by "extract the value:" do you mean whether 'a is true or false.

i need variable a,b,c,d ..
string str = Regex.Match(Readline, @"\(([^)]*)\)").Value;

Also "I need a and b to store in one list". What about c and d? Another list? Two separate lists? Can everything be in the same list with a, b, c, d columns?

You have to clarify what you need, your regex means nothing...describe in your words what you need. To clarify: for your given input above, write what output do you want / expect.

Check the below code :

C#

string test = "Sql==SqlString && Sql!=OracleStr || A==b&&b!=c&&D==m";
List<string> Variables = new List<string>();
MatchCollection Matches = Regex.Matches(test, @"(\w+)[=!]+(\w+)", RegexOptions.Compiled | RegexOptions.Singleline | RegexOptions.IgnoreCase);
foreach (Match ma in Matches)
{
    if (!Variables.Contains(ma.Groups[1].Value))
    Variables.Add(ma.Groups[1].Value);
    if (!Variables.Contains(ma.Groups[2].Value))
    Variables.Add(ma.Groups[2].Value);
}</string></string>
