Final answer:
To remove the last comma from a string in C#, you can use the TrimEnd method along with the comma as the character to trim.
Step-by-step explanation:
To remove the last comma from a string in C#, you can use the TrimEnd method along with the comma as the character to trim. Here is an example:
string str = "Hello, World, ";
str = str.TrimEnd(',');
Console.WriteLine(str); // Output: Hello, World
In this example, the TrimEnd method removes the last comma from the string str. It trims any trailing occurrences of the comma from the right side of the string.
In C#, to remove the last comma from a string, use StringBuilder and TrimEnd or Substring. For instance, with StringBuilder, set its length to exclude the last character (comma). Alternatively, with Substring, create a substring excluding the last character.
Both methods efficiently manipulate the string, ensuring the removal of the trailing comma. Choose the approach that best fits your coding style and requirements for concise and effective string manipulation in C#.
