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

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

Answer

To convert a set of floats to a set of strings in C#, you can use the Select() method from the LINQ library to project each float value to its string representation using the ToString() method.

✐ Examples

1 Convert a Set of Floats {1.1, 2.2, 3.3} to Strings

In this example,

First, we create a set of floats named floatSet1 with values {1.1f, 2.2f, 3.3f}.
Next, we use the Select() method from the LINQ library to project each float value in floatSet1 to its string representation. We do this by calling the ToString() method on each float element within the Select() method.
We store the result of this projection in a new set called stringSet1. The ToHashSet() method is used to convert the IEnumerable returned by Select() into a HashSet.
Finally, we iterate through stringSet1 and print each string value to the console to verify the conversion.

C# Program

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

class Program {
    static void Main() {
        HashSet<float> floatSet1 = new HashSet<float> { 1.1f, 2.2f, 3.3f };
        HashSet<string> stringSet1 = floatSet1.Select(f => f.ToString()).ToHashSet();
        
        foreach (var str in stringSet1) {
            Console.WriteLine(str);
        }
    }
}

Output

1.1
2.2
3.3

2 Convert a Set of Floats {4.5, 5.6, 6.7} to Strings

In this example,

First, we create a set of floats named floatSet2 with values {4.5f, 5.6f, 6.7f}.
Next, we use the Select() method from the LINQ library to project each float value in floatSet2 to its string representation. We do this by calling the ToString() method on each float element within the Select() method.
We store the result of this projection in a new set called stringSet2. The ToHashSet() method is used to convert the IEnumerable returned by Select() into a HashSet.
Finally, we iterate through stringSet2 and print each string value to the console to verify the conversion.

C# Program

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

class Program {
    static void Main() {
        HashSet<float> floatSet2 = new HashSet<float> { 4.5f, 5.6f, 6.7f };
        HashSet<string> stringSet2 = floatSet2.Select(f => f.ToString()).ToHashSet();
        
        foreach (var str in stringSet2) {
            Console.WriteLine(str);
        }
    }
}

Output

4.5
5.6
6.7
