嵌套的Select Case语句可以将select语句作为外部select语句的语句序列的一部分。 即使内部和外部选择的情况常数包含公共值,也不会出现冲突。
Dim a As Integer = 100 Dim b As Integer = 200 Select a Case 100 Proj.MsgDebug.Add("This is part of outer case ") Select Case b Case 200 Proj.MsgDebug.Add("This is part of inner case ") End Select End Select Proj.MsgDebug.Add("Exact value of a is : {0}", a) Proj.MsgDebug.Add("Exact value of b is : {0}", b) '返回结果:This Is part Of outer Case '返回结果:This Is part Of inner Case '返回结果:Exact value Of a Is : 100 '返回结果:Exact value Of b Is : 200 |
