EndOfStreamException 类
读操作试图超出流的末尾时引发的异常。
**命名空间:**System.IO
**程序集:**mscorlib（在 mscorlib.dll 中）
语法
声明
<SerializableAttribute> _
<ComVisibleAttribute(True)> _
Public Class EndOfStreamException
Inherits IOException
用法
Dim instance As EndOfStreamException
[SerializableAttribute]
[ComVisibleAttribute(true)]
public class EndOfStreamException : IOException
[SerializableAttribute]
[ComVisibleAttribute(true)]
public ref class EndOfStreamException : public IOException
/** @attribute SerializableAttribute() */
/** @attribute ComVisibleAttribute(true) */

备注
EndOfStreamException 使用值为 0x80070026 的 HRESULT COR_E_ENDOFSTREAM。
示例
下面的代码示例说明如何通过在 MemoryStream 类之上使用 BinaryReader 和 BinaryWriter 两个类，在内存中读写 Double 数据。
Imports System
Imports System.IO
Public Class BinaryRW
Shared Sub Main()
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.
Console.WriteLine("Writing data to the stream.")
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
Console.WriteLine("Verifying the written data.")
For i = 0 To upperBound
If binReader.ReadDouble() <> dataArray(i) Then
Console.WriteLine("Error writing data.")
Exit For
End If
Next i
Console.WriteLine("The data was written and verified.")
Catch ex As EndOfStreamException
Console.WriteLine("Error writing data: {0}.", _
ex.GetType().Name)
End Try
Finally
binWriter.Close()
End Try
End Sub
End Class
