例外
用户没有执行此操作的权限。
出现 I/O 错误。
设置操作在 Windows 之外的操作系统上调用。
示例
此示例演示 BufferHeight 和 BufferWidth 属性。 该示例报告设置为 300 行和 85 列的缓冲区大小的操作系统窗口的尺寸。
// This example demonstrates the Console.BufferHeight and
// Console.BufferWidth properties.
using namespace System;
int main()
{
Console::WriteLine( "The current buffer height is {0} rows.", Console::BufferHeight );
Console::WriteLine( "The current buffer width is {0} columns.", Console::BufferWidth );
}
/*
This example produces the following results:
The current buffer height is 300 rows.
The current buffer width is 85 columns.
*/
// This example demonstrates the Console.BufferHeight and
// Console.BufferWidth properties.
using System;
class Sample
{
public static void Main()
{
Console.WriteLine("The current buffer height is {0} rows.",
Console.BufferHeight);
Console.WriteLine("The current buffer width is {0} columns.",
Console.BufferWidth);
}
}
/*

// This example demonstrates the Console.BufferHeight and
// Console.BufferWidth properties.

注解
此属性定义 (行数或) 存储在控制台模式窗口访问的缓冲区中的行数。 相比之下, WindowHeight 属性定义在任何特定时间在控制台窗口中实际显示的行数。 如果实际写入缓冲区的行数超过了 属性定义的 WindowHeight 行数,则可以垂直滚动窗口,以便它显示等于 WindowHeight 属性且位于缓冲区中的任何位置的连续行数。
如果设置操作减小属性的值 BufferHeight ,则删除最上面的行。 例如,如果行数从 300 减少到 250,则删除行 0 到 49,现有行 50 到 299 将成为第 0 行到 249 行。
