StringBuilder::Append Method (array<Char>^, Int32, Int32)
Appends the string representation of a specified subarray of Unicode characters to this instance.
Assembly: mscorlib (in mscorlib.dll)
public: StringBuilder^ Append( array<wchar_t>^ value, int startIndex, int charCount )
A character array.
The starting position in value.
The number of characters to append.
Return ValueType: System.Text::StringBuilder^
A reference to this instance after the append operation has completed.
value is null, and startIndex and charCount are not zero.
charCount is less than zero.
startIndex is less than zero.
startIndex + charCount is greater than the length of value.
Enlarging the value of this instance would exceed MaxCapacity.
This method appends the specified range of characters in value to the current instance. If value is null and startIndex and count are both zero, no changes are made.
The StringBuilder object, as the following example illustrates.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
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.
