简单的代码改写,希望有人能帮一下.
原代码如下:
string[] Drive()
{
string[] tmpDrive = new string[5];

int tmp = 0;

DriveInfo[] allDrive = DriveInfo.GetDrives();

foreach (DriveInfo d in allDrive)
{
if (d.DriveType == DriveType.Fixed)
{
tmpDrive[tmp] = d.ToString() ;
tmp++;
}
}

return tmpDrive;
}

如何改写才能不用创建5个元素,而是根据动态创建TMPDRIVE数组?

就是类似于一下代码:
string[] Drive()
{
string[] tmpDrive; //就是这句

int tmp = 0;

DriveInfo[] allDrive = DriveInfo.GetDrives();

foreach (DriveInfo d in allDrive)
{
if (d.DriveType == DriveType.Fixed)
{
tmpDrive[tmp] = d.ToString() ;
tmp++;
}
}

return tmpDrive;
}

[解决办法]
DriveInfo[] allDrive = DriveInfo.GetDrives();

tmpDrive = new string[allDrive.Length]; //就是这句


[解决办法]
用这条语句试试,可以动态改变数组arrayName的长度
Array.Resize(ref arryName, length);
[解决办法]
楼上的正解
利用动态数组

我的使用习惯是用List <string> drivers = new List <string> ();

然后转换成字符串数组 drivers.ToArray();即可。
[解决办法]
string[] Drive()
{
int tmp = 0;

DriveInfo[] allDrive = DriveInfo.GetDrives();

string[] tmpDrive = new string[allDrive.length];

foreach (DriveInfo d in allDrive)
{
if (d.DriveType == DriveType.Fixed)
{
tmpDrive[tmp] = d.ToString() ;
tmp++;
}
}

return tmpDrive;
}
