StringReader.ReadToEnd StringReader.ReadToEnd StringReader.ReadToEnd StringReader.ReadToEnd Method

Definition

Reads all characters from the current position to the end of the string and returns them as a single string.

public:
 override System::String ^ ReadToEnd();
public override string ReadToEnd ();
override this.ReadToEnd : unit -> string
Public Overrides Function ReadToEnd () As String

Returns

The content from the current position to the end of the underlying string.

Exceptions

There is insufficient memory to allocate a buffer for the returned string.

Examples

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

void ReadText( TextReader^ textReader )
{
   Console::WriteLine( "From {0} - {1}", textReader->GetType()->Name, textReader->ReadToEnd() );
}


static void ReadText(TextReader textReader)
{
    Console.WriteLine("From {0} - {1}", 
        textReader.GetType().Name, textReader.ReadToEnd());
}
Shared Sub ReadText(aTextReader As TextReader)
    Console.WriteLine("From {0} - {1}", _
        aTextReader.GetType().Name, aTextReader.ReadToEnd())
End Sub

Remarks

This method overrides the TextReader.ReadToEnd method.

If the current method throws an OutOfMemoryException, the reader's position in the underlying string is advanced by the number of characters the method was able to read, but the characters already read into the internal ReadToEnd buffer are discarded. Because the position of the reader in the string cannot be changed, the characters already read are unrecoverable, and can be accessed only by reinitializing the StringReader. To avoid such a situation, use the Read method and store the read characters in a preallocated buffer.
