Assign a value to the expires value of the cookie. The read value is 0001-1-1 0:00:00. The trace debugging finds that the conversion is not a problem. The default value after the cookie is read is 0001-1-1 0:00:00. Solution: Set the expired items: Httpcookie = System. Web. httpcontext. Current. Request. Cook

Use arrays to solve the problem (1). Use arrays to solve the problem. Arrays are extremely common in programming, and array techniques are often used in non-array scenarios. Therefore, Arrays can be used as an important training place to solve problems with data structures.I. Basic Knowledge Overview

To get this topic, we will first think of using loops to complete.But not every operator is a "+" sign.Therefore, we are here to use (-1) of the I-side to do "+" "-" number control.The loop variable i is then treated as the denominator.Here we have the idea of the loop body is basically OK.It is important to note that the calculation results here are expressed in decimals, so it is not possible to define variables with int integers.The code is as foll
