How to get Substring before Specific Character in C# ?

Answer

To get the substring before a specific character in C#, you can use the `Substring` method along with the `IndexOf` method to find the position of the character.

✐ Examples

1 Substring Before '/' in "https://example.com/page"

In this example,

We create a variable named url with a value of "https://example.com/page".
We use the IndexOf method to find the position of '/'.
We use the Substring method with the starting index of 0 and the index of '/' to get the substring before the specified character.
Finally, we display the substring.

C# Program

using System;

class Program
{
    static void Main()
    {
        string url = "https://example.com/page";
        int index = url.IndexOf('/');
        string substring = url.Substring(0, index);
        Console.WriteLine("Substring before '/': " + substring);
    }
}

Output

Substring before '/': https:

2 Substring Before ',' in "Hello,World"

In this example,

We create a variable named str with a value of "Hello,World".
We use the IndexOf method to find the position of ','.
We use the Substring method with the starting index of 0 and the index of ',' to get the substring before the specified character.
Finally, we display the substring.

C# Program

using System;

class Program
{
    static void Main()
    {
        string str = "Hello,World";
        int index = str.IndexOf(',');
        string substring = str.Substring(0, index);
        Console.WriteLine("Substring before ',': " + substring);
    }
}

Output

Substring before ',': Hello
