For an example of creating a file and writing text to a file, see How to: Write Text to a File. For an example of reading text from a file, see How to: Read Text from a File. For an example of reading from and writing to a binary file, see How to: Read and Write to a Newly Created Data File.

Capacity is the buffer length for system-provided byte arrays. Capacity cannot be set to a value less than the current length of the stream.

This code example is part of a larger example provided for the MemoryStream class.

// Write the stream properties to the console.
Console.WriteLine(
    "Capacity = {0}, Length = {1}, Position = {2}\n",
    memStream.Capacity.ToString(), 
    memStream.Length.ToString(), 
    memStream.Position.ToString());

// Write the stream properties to the console.
Console.WriteLine(
    "Capacity = {0}, Length = {1}, Position = {2}\n", 
    (new Integer( memStream.get_Capacity())).ToString(),
    (new Long ( memStream.get_Length())).ToString(),
    (new Long ( memStream.get_Position())).ToString());
