從C中的路徑字符串獲取文件名＃

Question

我在WPF C＃中編寫程序。我有例如以下路徑：

C:\Program Files\hello.txt 

，我想輸出「你好」從它。

該路徑是從數據庫提取的字符串。目前我使用下面的方法（從程分裂的「\」然後由再次分裂「」）：

string path = "C:\\Program Files\\hello.txt"; 
string[] pathArr = path.Split('\\'); 
string[] fileArr = pathArr.Last().Split('.'); 
string fileName = fileArr.Last().ToString(); 

它的工作原理，但我認爲應該有更短和更智能的解決了這一點。任何想法？

Answer 1

Path.GetFileName

Path.GetFileNameWithoutExtension

的Path類是美好的。

Answer 2

您可以使用Path API如下：

var filenNme = Path.GetFileNameWithoutExtension([File Path]); 

更多信息：Path.GetFileNameWithoutExtension

Answer 3

嘗試

fileName = Path.GetFileName (path);

Answer 4

試試這個：

string fileName = Path.GetFileNameWithoutExtension(@"C:\Program Files\hello.txt"); 

這將爲fileName返回「hello」。

Answer 5

嘗試

System.IO.Path.GetFileNameWithoutExtension(path); 

演示

string fileName = @"C:\mydir\myfile.ext"; 
string path = @"C:\mydir\"; 
string result; 

result = Path.GetFileNameWithoutExtension(fileName); 
Console.WriteLine("GetFileNameWithoutExtension('{0}') returns '{1}'", 
    fileName, result); 

result = Path.GetFileName(path); 
Console.WriteLine("GetFileName('{0}') returns '{1}'", 
    path, result); 

// This code produces output similar to the following: 
// 
// GetFileNameWithoutExtension('C:\mydir\myfile.ext') returns 'myfile' 
// GetFileName('C:\mydir\') returns ''

Answer 6

var fileNameWithoutExtension = Path.GetFileNameWithoutExtension(path); 

Path.GetFileNameWithoutExtension

Answer 7

string Location = "C:\\Program Files\\hello.txt"; 

string FileName = Location.Substring(Location.LastIndexOf('\\') + 
    1); 

Answer 8

試試這個，

string FilePath=@"C:\mydir\myfile.ext"; 
string Result=Path.GetFileName(FilePath);//With Extension 
string Result=Path.GetFileNameWithoutExtension(FilePath);//Without Extension 

Answer 9

Namespace: using System.IO; 
//use this to get file name dynamically 
string filelocation = Properties.Settings.Default.Filelocation; 
//use this to get file name statically 
//string filelocation = @"D:\FileDirectory\"; 
string[] filesname = Directory.GetFiles(filelocation); //for multiple files 

Your path configuration in App.config file if you are going to get file name dynamically - 

    <userSettings> 
     <ConsoleApplication13.Properties.Settings> 
      <setting name="Filelocation" serializeAs="String"> 
      <value>D:\\DeleteFileTest</value> 
      </setting> 
       </ConsoleApplication13.Properties.Settings> 
     </userSettings>
