Implementation of obtaining various file names in C#

C# Get various file names

1. C# obtains the file name with suffix, suffix name, and file name according to the absolute path.

 string str =" E:\test\";
                string filename = (str);//file name ""                string extension = (str);//Extension ".aspx"                string fileNameWithoutExtension = (str);// Filename without extension “Default”

2. C# obtains the file name, suffix name, and file name with the absolute path, and use the Split function.

 string str = =" E:\test\";
                char[] delimiterChars = { '.', '\\' };
                string[] Mystr = (delimiterChars);
                string sheetName = Mystr[ - 2];);// Filename without extension “Default”

3. C# get file name and extension

string aFirstName = (("\\") + 1, ((".") - ("\\") - 1));  //file namestring aLastName = ((".") + 1, ( - (".") - 1));   //Extension

Something else is to use Substring to intercept

 (("\\") + 1,  - 1 - ("\\"));
 (("."),  - ("."));

Or use

This will allow you to get the directory path where the file is located

string path1 = () + @"\";
string path = ("C:\My Document\path\");    //Get only file names

string fullPath = @"\WebSite1\";
string filename = (fullPath);//file name  ""string extension = (fullPath);//Extension ".aspx"string fileNameWithoutExtension = (fullPath);// Filename without extension “Default”

(filePath)       //Return the file name with extension(filePath)     //Return file name without extension(filePath)     //Return to the directory where the file is located

4. Other methods

a. Get the full path of the current process, including the file name (process name).

string str = ().;
result: X:\xxx\xxx\ (.exeThe directory where the file resides+.exefile name)

b. Get the full path of the main module to which the new Process component is associated with the currently active process, including the file name (process name).

string str = ().;
result: X:\xxx\xxx\ (.exeThe directory where the file resides+.exefile name)

c. Get and set the fully qualified path to the current directory (i.e. the directory from which the process starts).

string str = ;
result: X:\xxx\xxx (.exeThe directory where the file resides)

d. Get the base directory of the current application domain of the current Thread, which is used by the assembly conflict resolver to detect the assembly.

string str = ;
result: X:\xxx\xxx\ (.exeThe directory where the file resides+"\")

e. Get and set the name of the directory containing the application.

string str = ;
result: X:\xxx\xxx\ (.exeThe directory where the file resides+"\")

f. Get the path to the executable file that started the application, excluding the name of the executable file.

string str = ;
result: X:\xxx\xxx (.exeThe directory where the file resides)

g. Get the path to the executable file that started the application, including the name of the executable file.

string str = ;
result: X:\xxx\xxx\ (.exeThe directory where the file resides+.exefile name)

C# Get all folder names in the specified folder

 public static string[] GetFilePath(string path)
    {
        if ((path))
        {
            //File path            string[] dir = (path);
            //file name            string[] names = new string[];
            for (int i = 0; i &lt; ; i++)
            {
                //Name of the assignment file                names[i] = (dir[i]);
            }
            return names;
        }
        else
        {
            ("Path not found");
            return null;
        }
    }
