Append Method (Char, Int32)

StringBuilder::Append Method (Char, Int32)

Appends a specified number of copies of the string representation of a Unicode character to this instance.

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

public:
StringBuilder^ Append(
	wchar_t value, 
	int repeatCount
)

Parameters

value
Type: System::Char

The character to append.

repeatCount
Type: System::Int32

The number of times to append value.

Return Value

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

ExceptionCondition
ArgumentOutOfRangeException

repeatCount is less than zero.

-or-

Enlarging the value of this instance would exceed MaxCapacity.

OutOfMemoryException

Out of memory.

The Append(Char, Int32) 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.
