Remember that an array's data type is never the same as that of its elements. You can find out the data type of either an array or its elements in several ways.You can call the Object.GetType method on the variable to receive a Type object for the run-time type of the variable....
To determine the data type of an array Call TypeName on the array name. Do not follow the array name with parentheses, because you are requesting the type of the array itself. 复制 Dim thisTwoDimArray(,) As Integer = New Integer(9, 9) {} MsgBox("Type of thisTwoDimArray is " & ...

data_type array_id [ index_type ]; data_type是数组元素的数据类型。 array_id是要声明的数组的名称。 index_type是要用作索引的数据类型。 Queues 队列是大小可变的有序元素的集合。队列中的每个元素都由一个序号表示,该序号表示其在队列中的位置,0表示第一个,$表示最后一个。
Array data type Important The Array data type can be used only in search indexes. Data tables do not support the Array data type. You can use the Array data type in the same manner you use a non-Array data type. When you use an Array field to query data, a row of data is returne...

Array.isArray 数组是基于对象的,不构成单独的语言类型。 所以typeof 不能帮助从数组中区分出普通对象: alert(typeof {}); // object alert(typeof []); // same ……但是数组经常被使用,因此有一种特殊的方法用于判断:Array.isArray(value)。如果 value 是一个数组,则返回 true;否则返回 false。
