I have 2 strings Str1 and Str2

When I am comparing these two strings.

This If condition returning false, why it is returning false as substring in Str2 is present in Str1.

What I have tried:

Str1="ABC Properitory Limited";
Str2="(Properitory Limited)+/g";

If(Str1.Contains(Str2)){
code;
}

Str2 is NOT in Str1.

In str2 you have a pair of parentheses and "+/g", they do not exist in str1.

You probably are confused with Regex functionality, see: C# Regex.Match Examples[^]
.Contains() just searches for a string, see: C# Contains String Method[^]

If as Rick suggests you are confusing it with a Regex comparison you would
have to do something like this to test if the pattern exists in the testdata.

C#

string testdata = "ABC Properitory Limited XYZ";
string pattern = @".*Properitory\s+Limited.*";

Match match = Regex.Match(testdata, pattern);

if (match.Success)
{
    Console.WriteLine("Pattern exists in str1");
}
else
{
    Console.WriteLine("Pattern does not found in str1");
}
