Position Property

UnmanagedMemoryStream.Position Property

Gets or sets the current position in a stream.

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

public override long Position { get; set; }

Property Value

Type: System.Int64
The current position in the stream.

ExceptionCondition
ObjectDisposedException

The stream is closed.

ArgumentOutOfRangeException

The position is set to a value that is less than zero, or the position is larger than MaxValue or results in overflow when added to the current pointer.

When a stream is initialized, this property is set to zero.

Although you can set the position of the stream beyond the stream's capacity, you will not be able to access that area using the Read and Write methods. Read will return 0 and Write will throw a NotSupportedException. This support is primarily for design and code compatibility with basic stream operations.
