C#中出现"'System.IO.FileSystemInfo.FullPath‘因其保护级别而无法访问“错误

Question

我有一个类似如下的C#程序。但它失败了。错误是'System.IO.FileSystemInfo.FullPath‘由于其保护级别而无法访问。FullPath用蓝色下划线。

protected void Main(string[] args)
{
    DirectoryInfo parent = new DirectoryInfo(@"C:\Users\dell\Desktop\rename");
    foreach (DirectoryInfo child in parent.GetDirectories())
    {
        string newName = child.FullPath.Replace('_', '-');

        if (newName != child.FullPath)
        {
            child.MoveTo(newName);
        }
    }
}

Answer 1

您要查找的属性名为FullName，而不是FullPath

static void Main()
{
    DirectoryInfo parent = new DirectoryInfo(@"C:\Users\dell\Desktop\rename");
    foreach (DirectoryInfo child in parent.GetDirectories())
    {
        string newName = child.FullName.Replace('_', '-');

        if (newName != child.FullName)
        {
            child.MoveTo(newName);
        }
    }
}

Answer 2

尝试使用FullName而不是FullPath：

这对您来说应该是可行的:)
