This can override both the order of precedence and the left associativity. Visual Basic always performs operations that are enclosed in parentheses before those outside. However, within parentheses, it maintains ordinary precedence and associativity, unless you use parentheses within the parentheses. The...
由于此行为,在 Visual Basic 中,运算符被称为左结合。 运算符重写和关联性 可以使用括号来强制在其他部分中计算表达式。 这可以覆盖优先级顺序和左侧相关性。 Visual Basic 始终执行括在括号内的操作。 但在括号中,它将保持普通的优先级和关联性,除非在括号内使用括号。 下面的示例对此进行了演示。
The element on the left side of the += operator can be a simple scalar variable, a property, or an element of an array. The variable or property cannot be ReadOnly (Visual Basic). The += operator assigns the value on its right to the variable or property on its left....

Notice that when a Boolean value is concatenated to a String, Visual Basic concatenates the string "False" or "True" on the basis of the Boolean's value. The chart in Fig. 3.15 displays the precedence of the Visual Basic operators introduced thus far. The operators are shown from top to...
