public static DriveInfoSystem GetInfo(string drive)
{
long result, available, total, free;
result = GetDiskFreeSpaceEx(drive, out available, out total, out free);
return new DriveInfoSystem(drive, result, available, total, free);
}
}
public struct DriveInfoSystem
{
public readonly string Drive;
public readonly long Result;
public readonly long Available;
public readonly long Total;
public readonly long Free;
public DriveInfoSystem(string drive, long result, long available, long total, long free)
{
this.Drive = drive;
this.Result = result;
this.Available = available;
this.Total = total;
this.Free = free;
}
}
可以通过
DriveInfoSystem info = DriveInfo.GetInfo("c:");来获得指定磁盘的开销情况
11.如何获得不区分大小写的子字符串的索引位置
1)通过将两个字符串转换成小写之后使用字符串的IndexOf方法:
string strParent = "The Codeproject site is very informative.";
string strChild = "codeproject";
// The line below will return -1 when expected is 4.
int i = strParent.IndexOf(strChild);
// The line below will return proper index
int j = strParent.ToLower().IndexOf(strChild.ToLower());
2)
一种更优雅的方法是使用System.Globalization命名空间下面的CompareInfo类的IndexOf方法:
using System.Globalization;
string strParent = "The Codeproject site is very informative.";
string strChild = "codeproject";
// We create a object of CompareInfo class for a neutral culture or a culture insensitive object
