c# using的用法using (FileStream output = File.Create("binarydata.dat"))using (BinaryWriter writer = new BinaryWriter(output)){writer.Write(intValue);writer.Write(stringValue);writer.Write(byteArray);writer.Write(floatValue);writer.Write(charValue)
c# using的用法
using (FileStream output = File.Create("binarydata.dat"))
using (BinaryWriter writer = new BinaryWriter(output))
{
writer.Write(intValue);
writer.Write(stringValue);
writer.Write(byteArray);
writer.Write(floatValue);
writer.Write(charValue);
}
我不是很懂第一行,为什么分号都不用?

c# using的用法using (FileStream output = File.Create("binarydata.dat"))using (BinaryWriter writer = new BinaryWriter(output)){writer.Write(intValue);writer.Write(stringValue);writer.Write(byteArray);writer.Write(floatValue);writer.Write(charValue)
c#中,using 关键字有两个主要用途:
作为指令,用于为命名空间创建别名或导入其他命名空间中定义的类型.
1、引入命名空间,如using System.IO;
2、为命名空间或类型创建别名.这称为“using 别名指令”.
如using Project = PC.MyCompany.Project;
作为语句,用于定义一个范围,在此范围的末尾将释放对象.
如你的代码using (FileStream output = File.Create("binarydata.dat"))
{
} 用完之后output会自动释放,等效于output.close();

关于C#中using的用法我在TCP服务器编程中看到了using这样的用发 using(FileStream stream=fileInfo.OpenRead())这里用using c# using的用法using (FileStream output = File.Create(binarydata.dat))using (BinaryWriter writer = new BinaryWriter(output)){writer.Write(intValue);writer.Write(stringValue);writer.Write(byteArray);writer.Write(floatValue);writer.Write(charValue) c#里的USING语句是什么意思using (sdr = cmd.ExecuteReader(CommandBehavior.CloseConnection)) { dt.Load(sdr); } using 关于c# using systemusing System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Text;using System.Windows.Forms; Designed和 using 的用法是什么Designed using theeasy-to-follow For Dummies format c#高手看看什么问题 using System; using System.Collections.Generic; using System.ComponentModel; usiusing System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Text;using System C# using用法 using(实例化对象){.}using语句,定义一个范围,在范围结束时处理对象.当在某个代码段中使用了类的实例,而希望无论因为什么原因,只要离开了这个代码段就自动调用这个类实例的Dispo 求0-100所有的质数用c#编写using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Text;using System.Windows.Forms;namespace WindowsApplication2{ public partial class For using的翻译 using的意思 using language的意思 C#语言环境,这个using有什么作用啊?
