Hi
I have a string array, from which I want part of strings to bind dropdownlist

Ex:

C#

string[] strArray = new string[10];
          
strArray[0] = "C:\MyFolder\Software";
strArray[1] = "C:\MyFolder\Admin";
strArray[2] = "C:\MyFolder\Accounts";
strArray[3] = "C:\MyFolder\HR";
strArray[4] = "C:\MyFolder\Maintainece";

From this string array i need "Software,Admin,Accounts,HR,Maintainece"
these strings to bind in dropdownlist without using foreach or for loop.

I need this using linq technique.. Pls help me

C#

string[] strArray = new string[5];
strArray[0] = @"C:\MyFolder\Software";
strArray[1] = @"C:\MyFolder\Admin";
strArray[2] = @"C:\MyFolder\Accounts";
strArray[3] = @"C:\MyFolder\HR";
strArray[4] = @"C:\MyFolder\Maintainece";

foreach (string node in strArray)
{
    string[] strpart =node.Split('\\');
    DropdownList1.Items.Add(strpart[strpart.Length-1]);
}

Get last string By this code

The following LINQ expression

C#

IEnumerable<string> ItemList = strArray
    .Where (a => a != null && a.Contains('\\'))
    .Select (a => a.Substring(a.LastIndexOf('\\')+1));

gives a collection strings, which can be bound to DropDownList

for getting splited string you can use Split method of string datatype.
for more information on Split method can see this.
Split Method[^]

you can go like this.

C#

string[] strArray = new string[5];
strArray[0] = @"C:\MyFolder\Software";
strArray[1] = @"C:\MyFolder\Admin";
strArray[2] = @"C:\MyFolder\Accounts";
strArray[3] = @"C:\MyFolder\HR";
strArray[4] = @"C:\MyFolder\Maintainece";

foreach (string str in strArray)
{
    string[] words =str.Split('\\');
    Response.Write(words[2] + ",<br>");
}
