There are operators for comparing numeric values, operators for comparing strings, and operators for comparing objects. All three types of operators are discussed herein. Comparing Numeric Values Visual Basic compares numeric values using six numeric comparison operators. Each operator takes as operands ...
The following are the comparison operators defined in Visual Basic. < operator <= operator > operator >= operator = operator <> operator Is Operator (Visual Basic) IsNot Operator Like Operator These operators compare two expressions to determine whether or not they are equal, and if not, how...
Module comparison_operators Sub Main() Dim a As Integer = 21 Dim b As Integer = 10 If (a = b) Then Console.WriteLine("Line 1 - a is equal to b") Else Console.WriteLine("Line 1 - a is not equal to b") End If If (a < b) Then...
Relational operators are also called comparison operators. Program.vb Console.WriteLine(3 < 4) ' Prints True Console.WriteLine(3 = 4) ' Prints False Console.WriteLine(4 >= 3) ' Prints True As we already mentioned, the relational operators return boolean values. Note that in Visual Basic, ...
不過,如果您設定 Option Strict Off,則 Visual Basic 會允許進行隱含縮小轉換,但可能導致資料或精確度意外遺失。 基於這個理由,建議您在撰寫生產程式碼時使用 Option Strict On。 如需詳細資訊,請參閱 Widening and Narrowing Conversions。 另請參閱 算術運算子 位元移位運算子 Comparison Operators in Visual Basic...
