The following example demonstrates obtaining a substring from a string.
using namespace System; using namespace System::Collections; int main() { array<String^>^info = {"Name: Felica Walker","Title: Mz.","Age: 47","Location: Paris","Gender: F"}; int found = 0; Console::WriteLine( "The initial values in the array are:" ); IEnumerator^ myEnum1 = info->GetEnumerator(); while ( myEnum1->MoveNext() ) { String^ s = safe_cast<String^>(myEnum1->Current); Console::WriteLine( s ); } Console::WriteLine( "\nWe want to retrieve only the key information. That is:" ); IEnumerator^ myEnum2 = info->GetEnumerator(); while ( myEnum2->MoveNext() ) { String^ s = safe_cast<String^>(myEnum2->Current); found = s->IndexOf( ":" ); Console::WriteLine( s->Substring( found + 1 )); } } // The example displays the following output to the console: // The initial values in the array are: // Name: Felica Walker // Title: Mz. // Age: 47 // Location: Paris // Gender: F // // We want to retrieve only the key information. That is: // Felica Walker // Mz. // 47 // Paris // F
