c# maui

In C# (including .NET MAUI), if you have:

var var1 = "Acc_det(acc_code)";

and you want to extract the value inside the parentheses (acc_code in this example), you can use a regular expression or string parsing.

Option 1 – Using Regex

using System.Text.RegularExpressions;

string var1 = "Acc_det(acc_code)";

// Pattern: match text inside parentheses
var match = Regex.Match(var1, @"\((.*?)\)");

if (match.Success)
{
    string valueInside = match.Groups[1].Value;
    Console.WriteLine(valueInside); // Output: acc_code
}

Option 2 – Using String Methods

string var1 = "Acc_det(acc_code)";

int startIndex = var1.IndexOf('(') + 1;
int endIndex = var1.IndexOf(')');

if (startIndex > 0 && endIndex > startIndex)
{
    string valueInside = var1.Substring(startIndex, endIndex - startIndex);
    Console.WriteLine(valueInside); // Output: acc_code
}

? When to use which?

Regex → cleaner for patterns, even if string format changes slightly.
String Methods → faster and fine for simple cases like this.
