Stream.CanRead Property
.NET Framework (current version)
When overridden in a derived class, gets a value indicating whether the current stream supports reading.
Assembly: mscorlib (in mscorlib.dll)
If a class derived from Stream does not support reading, calls to the Read, ReadByte, and BeginRead methods throw a NotSupportedException.
If the stream is closed, this property returns false.
The following is an example of using the CanRead property.
using System; using System.IO; class TestRW { public static void Main(String[] args) { FileStream fs = new FileStream("MyFile.txt", FileMode.OpenOrCreate, FileAccess.Read); if (fs.CanRead && fs.CanWrite) { Console.WriteLine("MyFile.txt can be both written to and read from."); } else if (fs.CanRead) { Console.WriteLine("MyFile.txt is not writable."); } } }
