C# Regular Expression need help

I try to find a part of a search word in a string variable with regular expression.

Here is the string variable content : 

string s_Var = "[ Object[Key='o_Module.Id'].Text ]"

[, ], ', ', and . always there , but not Key=, Object and Text. (Can be different). I want to determine the part between ' and ' like 'o_Module.Id'

I only want to take the part between ' and '

Can you help me to determine the pattern i need ?

Exemple :

string s_Original_Text = "[ Object[Key='o_Module.Id'].Text ]"

? = i don't know the value can be

[ ?[??'o_Module.?].? ]

I think that this should usually do it, assuming there's only ever one set of single-quotes:

System.Text.RegularExpressions.Match result = System.Text.RegularExpressions.Regex.Match("[ Object[Key='o_Module.Id'].Text ]", "'([^']*)'");

If you want to add that optional stuff:

result = System.Text.RegularExpressions.Regex.Match("[ Object[Key='o_Module.Id'].Text ]", @"\[ (?:Object)?\[(?:Key=)?'([^']*)'\]\.(?:Text)? \]");

try this code:

var s = "[['o_Module.Id'].Text]"; 
//"[Object[Key='o_Module.Id'].Text]"; //ALSO MATCHES THIS
var r = new System.Text.RegularExpressions.Regex(@"(\[?.*\[?')(.*)('.*)");
var m = r.Match(s);
if (m.Success)
{
    //0 contains whole string
    Console.WriteLine(m.Groups[2].Value); //Prints o_Module.Id
}

\[[^']*?'([^']+)

The o_Module.id value would be in the first capturing group.

If the single quotes are always present in the form you have shown above, why not just look for the first index of ' using SubString? From what I see in your description using regular expressions here is overkill.
