我還沒有與任何代碼的問題下面。 (相對路徑必須以'/'或'\'開頭)。
private bool IsValidPath(string path, bool allowRelativePaths = false)
{
bool isValid = true;
try
{
string fullPath = Path.GetFullPath(path);
if (allowRelativePaths)
{
isValid = Path.IsPathRooted(path);
}
else
{
string root = Path.GetPathRoot(path);
isValid = string.IsNullOrEmpty(root.Trim(new char[] { '\\', '/' })) == false;
}
}
catch(Exception ex)
{
isValid = false;
}
return isValid;
}
例如,這些將返回false:
IsValidPath("C:/abc*d");
IsValidPath("C:/abc?d");
IsValidPath("C:/abc\"d");
IsValidPath("C:/abc<d");
IsValidPath("C:/abc>d");
IsValidPath("C:/abc|d");
IsValidPath("C:/abc:d");
IsValidPath("");
IsValidPath("./abc");
IsValidPath("./abc", true);
IsValidPath("/abc");
IsValidPath("abc");
IsValidPath("abc", true);
而這些將返回true:
IsValidPath(@"C:\\abc");
IsValidPath(@"F:\FILES\");
IsValidPath(@"C:\\abc.docx\\defg.docx");
IsValidPath(@"C:/abc/defg");
IsValidPath(@"C:\\\//\/\\/\\\/abc/\/\/\/\///\\\//\defg");
IsValidPath(@"C:/abc/def~`[email protected]#$%^&()_-+={[}];',.g");
IsValidPath(@"C:\\\\\abc////////defg");
IsValidPath(@"/abc", true);
IsValidPath(@"\abc", true);
