index is less than zero or greater than the length of this instance.

OutOfMemoryException

Enlarging the value of this instance would exceed MaxCapacity.

Double.ToString is used to get a string representation of value. Existing characters are shifted to make room for the new text. The capacity of this instance is adjusted as needed.

Notes to Callers

In the .NET Framework 3.5 Service Pack 1 and earlier versions, calls to this method threw an ArgumentOutOfRangeException if inserting value would cause the object's total length to exceed MaxCapacity. Starting with the .NET Framework 4, the method throws an OutOfMemoryException.

The following example demonstrates the Insert method.
