Compare strings using StringComparison.OrdinalIgnoreCase

Through this blog I will show you the tricks to compare the string in C#.

Usually, When people compare the two strings (Don't know whether, if they are in upper case or lower case), they do it like this..

string FirstString = "GAURAV";
string SecondString = "gaurav";

if (FirstString .ToUpper() == SecondString.ToUpper())

{

Response.Write("true");

}

Comparing the two string using the above code will increase the additional memory allocation overhead on the compiler.

The above task can be accomplish by avoiding string allocation overhead like this.

string FirstString = "GAURAV";
string SecondString = "gaurav";
if (FirstString.Equals(SecondString, StringComparison.OrdinalIgnoreCase))
{
Response.Write("Matched");
}

In the above code,StringComparison.OrdinalIgnoreCase will lead to compare the string by ignoring it's case.

So, Now your code to compare the two strings:

if (FirstString .ToUpper() == SecondString.ToUpper())
