✅ string.Join returns System.Int32[]

In my constructor I am getting

T desiredValue

T desiredValue

T desiredValue

T desiredValue.
In this case

T

T is

int[]

int[]

int[]

int[].
When debugging the below code:

string desiredValue;
if (typeof(T) == typeof(int[]))
{
    format = "{0} = [{1}]\n";
    desiredValue = string.Join(", ", this.desiredValue);
}

string desiredValue;
if (typeof(T) == typeof(int[]))
{
    format = "{0} = [{1}]\n";
    desiredValue = string.Join(", ", this.desiredValue);
}

string desiredValue;
if (typeof(T) == typeof(int[]))
{
    format = "{0} = [{1}]\n";
    desiredValue = string.Join(", ", this.desiredValue);
}

string desiredValue;
if (typeof(T) == typeof(int[]))
{
    format = "{0} = [{1}]\n";
    desiredValue = string.Join(", ", this.desiredValue);
}

I end up getting

System.Int32[]

System.Int32[]

System.Int32[]

System.Int32[] any idea why?
