What is the purpose of assert() in C#?

While developing an application, there are high probabilities for logical errors to occur. During development phase, you can trap those errors using assert method.

namespace Application1 {
public class sampleClass {
public static void Main() {
Console.WriteLine("Enter the number:");
int sampleNum = Int32.Parse(Console.ReadLine());
Debug.Assert(sampleNum > 0);
float var1 = 100 / sampleNum;
Console.WriteLine("Result = {0}", var1);
}
}
}

Execute this program and enter the number as 0. Now the condition sampleNum>0 will fail. Hence you will get the following assertion failure message:
