StringBuilder::Equals Method (StringBuilder)
Visual Studio 2010
Returns a value indicating whether this instance is equal to a specified object.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- sb
- Type: System.Text::StringBuilder
An object to compare with this instance, or nullptr.
Return Value
Type: System::Booleantrue if this instance and sb have equal string, Capacity, and MaxCapacity values; otherwise, false.
The following code uses the Equals method to check whether two StringBuilder objects are equal. The method is called repeatedly after small changes are made to each object, and the results are displayed to the console.
using namespace System; using namespace System::Text; int main() { StringBuilder^ sb1 = gcnew StringBuilder( "abc" ); StringBuilder^ sb2 = gcnew StringBuilder( "abc",16 ); Console::WriteLine(); Console::WriteLine( "a1) sb1->Length = {0}, sb1->Capacity = {1}", sb1->Length, sb1->Capacity ); Console::WriteLine( "a2) sb2->Length = {0}, sb2->Capacity = {1}", sb2->Length, sb2->Capacity ); Console::WriteLine( "a3) sb1 = \"{0}\", sb2 = \"{1}\"", sb1, sb2 ); Console::WriteLine( "a4) sb1 equals sb2: {0}", sb1->Equals( sb2 ) ); Console::WriteLine(); Console::WriteLine( "Ensure sb1 has a capacity of at least 50 characters." ); sb1->EnsureCapacity( 50 ); Console::WriteLine(); Console::WriteLine( "b1) sb1->Length = {0}, sb1->Capacity = {1}", sb1->Length, sb1->Capacity ); Console::WriteLine( "b2) sb2->Length = {0}, sb2->Capacity = {1}", sb2->Length, sb2->Capacity ); Console::WriteLine( "b3) sb1 = \"{0}\", sb2 = \"{1}\"", sb1, sb2 ); Console::WriteLine( "b4) sb1 equals sb2: {0}", sb1->Equals( sb2 ) ); Console::WriteLine(); Console::WriteLine( "Set the length of sb1 to zero." ); Console::WriteLine( "Set the capacity of sb2 to 51 characters." ); sb1->Length = 0; sb2->Capacity = 51; Console::WriteLine(); Console::WriteLine( "c1) sb1->Length = {0}, sb1->Capacity = {1}", sb1->Length, sb1->Capacity ); Console::WriteLine( "c2) sb2->Length = {0}, sb2->Capacity = {1}", sb2->Length, sb2->Capacity ); Console::WriteLine( "c3) sb1 = \"{0}\", sb2 = \"{1}\"", sb1, sb2 ); Console::WriteLine( "c4) sb1 equals sb2: {0}", sb1->Equals( sb2 ) ); } /* The example displays the following output: a1) sb1->Length = 3, sb1->Capacity = 16 a2) sb2->Length = 3, sb2->Capacity = 16 a3) sb1 = "abc", sb2 = "abc" a4) sb1 equals sb2: True Ensure sb1 has a capacity of at least 50 characters. b1) sb1->Length = 3, sb1->Capacity = 50 b2) sb2->Length = 3, sb2->Capacity = 16 b3) sb1 = "abc", sb2 = "abc" b4) sb1 equals sb2: False Set the length of sb1 to zero.
