StringBuilder::Append Method (array<Char>)

Appends the string representation of the Unicode characters in a specified array to this instance.

Namespace:  System.Text
Assembly:  mscorlib (in mscorlib.dll)

public:
StringBuilder^ Append(
	array<wchar_t>^ value
)

Parameters

value
Type: array<System::Char>

The array of characters to append.

Return Value

Type: System.Text::StringBuilder
A reference to this instance after the append operation has completed.

ExceptionCondition
ArgumentOutOfRangeException

Enlarging the value of this instance would exceed MaxCapacity.

This method appends all the characters in the specified array to the current instance in the same order as they appear in value. If value is nullptr, no changes are made.

The Append(array<Char>) method modifies the existing instance of this class; it does not return a new class instance. Because of this, you can call a method or property on the existing reference and you do not have to assign the return value to a StringBuilder object, as the following example illustrates.

No code example is currently available or this language may not be supported.

The capacity of this instance is adjusted as needed.

Notes to Callers

In the .NET Framework 4 and the .NET Framework 4.5, when you instantiate the StringBuilder object by calling the StringBuilder(Int32, Int32) constructor, both the length and the capacity of the StringBuilder instance can grow beyond the value of its MaxCapacity property. This can occur particularly when you call the Append and AppendFormat methods to append small strings.
