String::Equals Method (String, String)
Visual Studio 2010
Determines whether two specified String objects have the same value.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- a
- Type: System::String
The first string to compare, or nullptr.
- b
- Type: System::String
The second string to compare, or nullptr.
Return Value
Type: System::Booleantrue if the value of a is the same as the value of b; otherwise, false. If both a and b are nullptr, the method returns true.
The following example demonstrates the Equals method.
// Sample for String::Equals(Object) // String::Equals(String) // String::Equals(String, String) using namespace System; using namespace System::Text; int main() { StringBuilder^ sb = gcnew StringBuilder( "abcd" ); String^ str1 = "abcd"; String^ str2 = nullptr; Object^ o2 = nullptr; Console::WriteLine(); Console::WriteLine( " * The value of String str1 is '{0}'.", str1 ); Console::WriteLine( " * The value of StringBuilder sb is '{0}'.", sb ); Console::WriteLine(); Console::WriteLine( "1a) String::Equals(Object). Object is a StringBuilder, not a String." ); Console::WriteLine( " Is str1 equal to sb?: {0}", str1->Equals( sb ) ); Console::WriteLine(); Console::WriteLine( "1b) String::Equals(Object). Object is a String." ); str2 = sb->ToString(); o2 = str2; Console::WriteLine( " * The value of Object o2 is '{0}'.", o2 ); Console::WriteLine( " Is str1 equal to o2?: {0}", str1->Equals( o2 ) ); Console::WriteLine(); Console::WriteLine( " 2) String::Equals(String)" ); Console::WriteLine( " * The value of String str2 is '{0}'.", str2 ); Console::WriteLine( " Is str1 equal to str2?: {0}", str1->Equals( str2 ) ); Console::WriteLine(); Console::WriteLine( " 3) String::Equals(String, String)" ); Console::WriteLine( " Is str1 equal to str2?: {0}", String::Equals( str1, str2 ) ); } /* This example produces the following results: * The value of String str1 is 'abcd'. * The value of StringBuilder sb is 'abcd'. 1a) String::Equals(Object). Object is a StringBuilder, not a String. Is str1 equal to sb?: False 1b) String::Equals(Object). Object is a String. * The value of Object o2 is 'abcd'. Is str1 equal to o2?: True 2) String::Equals(String) * The value of String str2 is 'abcd'. Is str1 equal to str2?: True 3) String::Equals(String, String) Is str1 equal to str2?: True */
