how to see if a variable is in a class in c#
MyClass myClass = new MyClass();
try
{
// varToFind is the variable that you want to see if it is
// in the class
if (myClass.varToFind != "")
{
print("This variable name is in class");
}
else
{
print("The variable is in the class it is just set to nothing");
}
}
catch:
{
print("Variable is not in stringbuilder");
}c# check if object is instance of class
using System;
public interface IExample {}
public class BaseClass : IExample {}
public class DerivedClass : BaseClass {}
public class Example
{
public static void Main()
{
var interfaceType = typeof(IExample);
var base1 = new BaseClass();
var base1Type = base1.GetType();
var derived1 = new DerivedClass();
var derived1Type = derived1.GetType();
int[] arr = new int[11];
Console.WriteLine("Is int[] an instance of the Array class? {0}.",
typeof(Array).IsInstanceOfType(arr));
Console.WriteLine("Is base1 an instance of BaseClass? {0}.",
base1Type.IsInstanceOfType(base1));
Console.WriteLine("Is derived1 an instance of BaseClass? {0}.",
base1Type.IsInstanceOfType(derived1));
Console.WriteLine("Is base1 an instance of IExample? {0}.",
interfaceType.IsInstanceOfType(base1));
Console.WriteLine("Is derived1 an instance of IExample? {0}.",
interfaceType.IsInstanceOfType(derived1));
}
}
// The example displays the following output:
// Is int[] an instance of the Array class? True.
// Is base1 an instance of BaseClass? True.
// Is derived1 an instance of BaseClass? True.
// Is base1 an instance of IExample? True.
// Is derived1 an instance of IExample? True.Copyright © 2021 Codeinu
