示例1: if
obj1 = (Single)500;
if (a.Equals(obj1)) {
Console.WriteLine("The value type and reference type values are equal.");
}示例2:
// Initialize two floats with apparently identical values
float float1 = .33333f;
object float2 = 1/3;
// Compare them for equality
Console.WriteLine(float1.Equals(float2)); // displays false示例3:
// Initialize two floats with apparently identical values
float float1 = .33333f;
object float2 = (float) 1/3;
// Define the tolerance for variation in their values
float difference = Math.Abs(float1 * .0001f);
// Compare the values
// The output to the console indicates that the two values are equal
if (Math.Abs(float1 - (float) float2) <= difference)
Console.WriteLine("float1 and float2 are equal.");
else
Console.WriteLine("float1 and float2 are unequal.");示例4: Main
