On my computer the pipe shares its key with \. Keep in mind that OR will be evaluated after AND. It is possible to combine several boolean operators in a single statement; often you will find doing so to be of great value when creating complex expressions for if statements. What is !

IfError(1,2)第一个参数不是错误。 函数没有其他错误要检查,也没有默认返回值。 函数返回最后一个求值的value参数。1 IfError(1/0,2)第一个参数返回一个错误值(由于除数为零)。 函数对第二个参数求值并将其作为结果返回。2 IfError(10,20,30)第一个参数不是错误。 函数没有其他错误要检查,但有默认返回...
An if statement with an else part selects one of the two statements to execute based on the value of a Boolean expression, as the following example shows: C# Copy Run DisplayWeatherReport(15.0); // Output: Cold. DisplayWeatherReport(24.0); // Output: Perfect! void DisplayWeatherReport(do...
