Hi,

I was looking for a solution in C# where I could confirm that the Sub-string exists inside a long string.

Suppose I want to find that sub-string 'save' exists inside the string - 'To save the current HTML file' or not.

Can anyone provide C# code for this?

You may use
int index = htmlString.IndexOf(substring);

if index>=0 - substring found

or alternatively yourString.Contains(substring);
this will return true if substring exists in your string.

You could do something like the following if you merely want to confirm existence:
string test = "To save the current HTML file";
bool hasIt;
 
hasIt = test.Contains("save");
