public class EndOfStreamException : IOException
The EndOfStreamException type exposes the following members.
Constructors
Name | Description | |
---|---|---|
EndOfStreamException() | Initializes a new instance of the EndOfStreamException class with its message string set to a system-supplied message. | |
EndOfStreamException(String) | Initializes a new instance of the EndOfStreamException class with its message string set to message and its HRESULT set to COR_E_ENDOFSTREAM. | |
EndOfStreamException(String, Exception) | Initializes a new instance of the EndOfStreamException class with a specified error message and a reference to the inner exception that is the cause of this exception. |

Properties
Name | Description | |
---|---|---|
Data | Gets a collection of key/value pairs that provide additional user-defined information about the exception. (Inherited from Exception.) | |
HResult | Gets or sets HRESULT, a coded numerical value that is assigned to a specific exception. (Inherited from Exception.) | |
InnerException | Gets the Exception instance that caused the current exception. (Inherited from Exception.) | |
Message | Gets a message that describes the current exception. (Inherited from Exception.) | |
StackTrace | Gets a string representation of the frames on the call stack at the time the current exception was thrown. (Inherited from Exception.) |

Methods
Name | Description | |
---|---|---|
Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) | |
Finalize | Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) | |
GetBaseException | When overridden in a derived class, returns the Exception that is the root cause of one or more subsequent exceptions. (Inherited from Exception.) | |
GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) | |
GetType | Gets the runtime type of the current instance. (Inherited from Exception.) | |
MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) | |
ToString | Creates and returns a string representation of the current exception. (Inherited from Exception.) |

Remarks
EndOfStreamException uses the HRESULT COR_E_ENDOFSTREAM which has the value 0x80070026.
Examples
The following code example shows how to read and write Double data to memory by using the BinaryReader and BinaryWriter classes on top of the MemoryStream class.
Note: |
---|
To run this example, see Building Examples That Use a Demo Method and a TextBlock Control. |
Imports System.IO
Public Class Example
Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
Dim i As Integer
Const upperBound As Integer = 1000
' Create random data to write to the stream.
Dim dataArray(upperBound) As Double
Dim randomGenerator As New Random()
For i = 0 To upperBound
dataArray(i) = 100.1 * randomGenerator.NextDouble()
Next i
Dim binWriter As New BinaryWriter(New MemoryStream())
Try
' Write data to the stream.
outputBlock.Text &= "Writing data to the stream." & vbCrLf
For i = 0 To upperBound
binWriter.Write(dataArray(i))
Next i
' Create a reader using the stream from the writer.
Dim binReader As New BinaryReader(binWriter.BaseStream)
' Return to the beginning of the stream.
binReader.BaseStream.Position = 0
' Read and verify the data.
Try
outputBlock.Text &= "Verifying the written data." & vbCrLf
For i = 0 To upperBound
If binReader.ReadDouble() <> dataArray(i) Then
outputBlock.Text &= "Error writing data." & vbCrLf
Exit For
End If
Next i
outputBlock.Text &= "The data was written and verified." & vbCrLf
Catch ex As EndOfStreamException
outputBlock.Text &= String.Format("Error writing data: {0}.", _
ex.GetType().Name) & vbCrLf
End Try
Finally
binWriter.Close()
End Try
End Sub
