StringBuilder::Append Method (Char, Int32)
Appends a specified number of copies of the string representation of a Unicode character to this instance.
Assembly: mscorlib (in mscorlib.dll)
- Type: System::Char
The character to append.
- Type: System::Int32
The number of times to append value.
Return ValueType: System.Text::StringBuilder
A reference to this instance after the append operation has completed.
The 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.
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.
