关于c# 按字符读取文本文件的问题
想弄一个类似于读书的软件，需要从文本文件中，一次读出固定数量的字符，
需要怎么做啊，找来找去都找不到的说~谢谢了

既然用的是 ms 的东西，msdn这么好的资料库都不用？

.NET Framework 类库

StreamReader.Read 方法 [C#]请参见
StreamReader 类 | StreamReader 成员 | System.IO 命名空间 | C++ 托管扩展编程
语言
C#

C++

JScript

Visual Basic

全部显示
读取输入流中的下一个字符或下一组字符。

重载列表
读取输入流中的下一个字符并使该字符的位置提升一个字符。

受 .NET Framework 精简版的支持。

[Visual Basic] Overloads Overrides Public Function Read() As Integer
[C#] public override int Read();
[C++] public: int Read();
[JScript] public override function Read() : int;
从 index 开始，从当前流中将最多的 count 个字符读入 buffer。

受 .NET Framework 精简版的支持。

[Visual Basic] Overloads Overrides Public Function Read(Char(), Integer, Integer) As Integer
[C#] public override int Read(char[], int, int);
[C++] public: int Read(__wchar_t __gc[], int, int);
[JScript] public override function Read(Char[], int, int) : int;
示例
[Visual Basic, C#, C++] 下面的示例一次读取五个字符直至达到文件的末尾。

[Visual Basic, C#, C++] 注意 此示例显示如何使用 Read 的一个重载版本。有关其他可用示例，请参阅单独的重载主题。
