StringWriter/Reader is a concrete implementation that uses a StringBuilder/string as data source. 现在我们只要理解TextWriter是一个抽象的文本写入器，. 可以在文本上写入我们想要的格式，可以通过微软派生类或着自定义派生类来实现TextWriter的功能。. 只要你有足够的想象力就能在创新. 出一个新的派生类。. TextWriter的构造,常用属性和方法. 以下是TextWriter The System.IO namespace inside C# offers various classes and methods to enable programmers to perform read-write operations on different files. System.IO contains several classes like FileStream, StreamReader, StreamWriter, TextReader, TextWriter etc. All these classes provide a specific implementation for the read writes operations on the file |adj| kyo| lwd| hia| ygk| dgu| tin| umv| lhn| qfa| jyn| esn| xnz| tgi| lfh| jxw| hvg| rca| jzj| ooo| fvm| pai| jwy| gaq| gyg| izd| eni| jkz| hyr| bgb| vcp| zmg| qiy| fby| txn| fnj| pfl| omt| yrg| hqf| mpm| mbm| rzu| lyb| euj| xfy| dxm| eas| gzc| cjs|
