How to Convert a Set of Strings to a Set of Floats in C# - Step by Step Examples

How to Convert a Set of Strings to a Set of Floats in C# ?

Answer

To convert a set of strings to a set of floats in C#, you can use LINQ's Select method to parse each string to a float and then collect the results into a new set.


✐ Examples

1 Convert Set of Strings to Set of Floats Example 1

In this example,

  1. First, we create a set named stringSet using the HashSet class, which contains the string values "1.1", "2.2", and "3.3".
  2. Next, we use LINQ's Select method to parse each string in stringSet to a float using the lambda expression float.Parse(s).
  3. The result of Select is an IEnumerable<float> containing the parsed float values.
  4. We convert this IEnumerable to a set using the ToHashSet extension method.
  5. The resulting set of floats is stored in a variable called floatSet.
  6. Finally, we iterate through floatSet and print each float value.

C# Program

using System;
using System.Collections.Generic;
using System.Linq;

public class Program
{
    public static void Main()
    {
        HashSet<string> stringSet = new HashSet<string>(new string[] { "1.1", "2.2", "3.3" });
        HashSet<float> floatSet = stringSet.Select(s => float.Parse(s)).ToHashSet();

        foreach (float f in floatSet)
        {
            Console.WriteLine(f);
        }
    }
}

Output

1.1
2.2
3.3

2 Convert Set of Strings to Set of Floats Example 2

In this example,

  1. We start by creating a set named stringSet2 using the HashSet class, which contains the string values "4.4", "5.5", and "6.6".
  2. We then use LINQ's Select method to parse each string in stringSet2 to a float using the lambda expression float.Parse(s).
  3. The result of Select is an IEnumerable<float> containing the parsed float values.
  4. We convert this IEnumerable to a set using the ToHashSet extension method.
  5. The resulting set of floats is stored in a variable called floatSet2.
  6. Finally, we iterate through floatSet2 and print each float value.

C# Program

using System;
using System.Collections.Generic;
using System.Linq;

public class Program
{
    public static void Main()
    {
        HashSet<string> stringSet2 = new HashSet<string>(new string[] { "4.4", "5.5", "6.6" });
        HashSet<float> floatSet2 = stringSet2.Select(s => float.Parse(s)).ToHashSet();

        foreach (float f in floatSet2)
        {
            Console.WriteLine(f);
        }
    }
}

Output

4.4
5.5
6.6
