It is about ToString()
method because I want to dynamically get all props names and their values. I don't know if it is possible to do that inside of the current class.
It is not issue, however this
can be removed here:
var allProperties = GetType().GetProperties();
And set this
object as parameter for prop.GetValue(object? obj)
.
The whole code would look like this:
public override string ToString()
{
StringBuilder sb = new StringBuilder();
var allProperties = GetType().GetProperties();
foreach (var prop in allProperties)
{
sb.AppendLine($"Sum of {prop.Name} is: {prop.GetValue(this)}");
}
return sb.ToString();
}
An example can be seen here:
class A
{
public int Foo { get; set; }
}
class B : A
{
public string Bar { get; set; }
public override string ToString()
{
StringBuilder sb = new StringBuilder();
var allProperties = GetType().GetProperties();
foreach (var prop in allProperties)
{
sb.AppendLine($"Sum of {prop.Name} is: {prop.GetValue(this)}");
}
return sb.ToString();
}
}
and you can run the above code like this:
B c = new B() { Foo = 1, Bar = "2" };
string str = c.ToString();
