Hi Jhon,

You can also use below code.

string inString = "IN ('Test 123','12345','163')";
string result = inString.Replace("IN (", "").TrimEnd(')');

string outInput = "NOT IN ('Test 123','12345','163')";
string result1 = outInput.Replace("NOT IN (", "").TrimEnd(')');

Thanks

Easiest would be

var str1="IN ('Test 123','12345','163')";

var str2="NOT IN ('Test 123','12345','163')";
var res1=str1.Replace("IN","").Replace("(","").Replace(")","").Replace("NOT","").Replace(" ","");
var res2=str2.Replace("IN","").Replace("(","").Replace(")","").Replace("NOT","").Replace(" ","");

Or better create one extension method

public static MyExtensionForStrings
{
public static string RemoveSpecialAlphaSps(this string str)
{
  return str.Replace("IN","").Replace("(","").Replace(")","").Replace("NOT","").Replace(" ","");
}

}

use above extension method as

var res1=str1.RemoveSpecialAlphaSps();
var res2=str2.RemoveSpecialAlphaSps();

or best one

public static MyExtensionForStrings
{
public static string RemoveSpecialAlphaSps(this string str)
{
  return str.Replace("IN (", "").Replace("NOT","").TrimEnd(')');
}

}

Hello Jhon,

Use below code.

string inString = "IN ('Test 123','12345','163')";
int startIndex = inString.IndexOf("(") + 1;
int endIndex = inString.IndexOf(")");
string inStringResult = inString.Substring(startIndex, endIndex - startIndex).Trim();

string notInString = "NOT IN('Test 123','12345','163')";
int notInStringStartIndex = notInString.IndexOf("(") + 1;
int notInStringEndIndex = notInString.IndexOf(")");
string notInStringResult = notInString.Substring(notInStringStartIndex, notInStringEndIndex - notInStringStartIndex).Trim();

Thanks
