Scene: When you import more than one piece of data through Excel (insert multiple data at once into the database), to read, parse Excel, and loop into each piece of data, before inserting a piece of data to determine whether the data already exists, if there is a continue exit the current loop, into the next cycle. For example: Break : Jump out of the loop for

The while loop method described in the previous article is very common. We can set a counter to start the loop. At the beginning of each iteration, the counter is tested in the conditional expression. At the end of the loop, The while loop method described in the previous article is very common. We can set a counter to

The format of the for loop described earlier is as follows:For VARNAME in List;doStatement...DoneThe For loop in this format is the statement that assigns each value in the list to the variable varname, and then executes in the loop body. When no value in this list is copied to the variable varname, the loop ends.Here

Let me introduce you to the loop execution for loop in C # In this practice, we'll show you another important circular statement in C #, for loops. for (expression 1; expression 2; expression 3) { loop-body } Expression 1: Generally the assignment expression, gives the control variable an initial value; Expression 2: Logical expression,
