请教一下 VB.NET Select Case 的问题

[aeeq123]

在 vb.net 项目下用 Select Case String 反编译后变成了 IF Else，Select Case Integer 就不会 有什么办法可以优化一下
VB.NET 源码

 Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim mtd As String = Context.Request.QueryString("mtd")
        Dim text As String = mtd
        Select Case text
            Case "1"
                Context.Response.Write("1")
                Return
            Case "2"
                Context.Response.Write("2")
                Return
            Case "3"
                Context.Response.Write("3")
                Return
            Case "4"
                Context.Response.Write("4")
                Return
            Case "5"
                Context.Response.Write("5")
                Return
            Case "6"
                Context.Response.Write("6")
                Return
            Case "7"
                Context.Response.Write("7")
                Return
        End Select
        Context.Response.Write("else")
    End Sub

反编译，成了 IF ELSE 了

	Protected Sub Page_Load(sender As Object, e As EventArgs)
			Dim text As String = Me.Context.Request.QueryString("mtd")
			Dim text2 As String = text
			Dim left As String = text2
			If Operators.CompareString(left, "1", False) = 0 Then
				Me.Context.Response.Write("1")
				Return
			End If
			If Operators.CompareString(left, "2", False) = 0 Then
				Me.Context.Response.Write("2")
				Return
			End If
			If Operators.CompareString(left, "3", False) = 0 Then
				Me.Context.Response.Write("3")
				Return
			End If
			If Operators.CompareString(left, "4", False) = 0 Then
				Me.Context.Response.Write("4")
				Return
			End If
			If Operators.CompareString(left, "5", False) = 0 Then
				Me.Context.Response.Write("5")
				Return
			End If
			If Operators.CompareString(left, "6", False) = 0 Then
				Me.Context.Response.Write("6")
				Return
			End If
			If Operators.CompareString(left, "7", False) = 0 Then
				Me.Context.Response.Write("7")
				Return
			End If
			Me.Context.Response.Write("else")
		End Sub

C# 的就不会
源码

 public void ProcessRequest(HttpContext context)
        {
            string mtd = context.Request.QueryString["mtd"];
            switch (mtd)
            {
                case "1":
                    context.Response.Write("1");
                    break;
                case "2":
                    context.Response.Write("2"); break;
                case "3":
                    context.Response.Write("3"); break;
                case "4":
                    context.Response.Write("4"); break;
                case "5":
                    context.Response.Write("5"); break;
                case "6":
                    context.Response.Write("6"); break;
                case "7":
                    context.Response.Write("7"); break;
                default:
                    context.Response.Write("else"); break;
                    break;

            }
        }

反编译后

public void ProcessRequest(HttpContext context)
		{
			string mtd = context.Request.QueryString["mtd"];
			string text = mtd;
			switch (text)
			{
			case "1":
				context.Response.Write("1");
				return;
			case "2":
				context.Response.Write("2");
				return;
			case "3":
				context.Response.Write("3");
				return;
			case "4":
				context.Response.Write("4");
				return;
			case "5":
				context.Response.Write("5");
				return;
			case "6":
				context.Response.Write("6");
				return;
			case "7":
				context.Response.Write("7");
				return;
			}
			context.Response.Write("else");
		}

我感兴趣的是你用的什么反编译软件？ 能否给个链接，下来玩玩

反编译用的是ILSpy，直接百度搜索

case里的return是多余的
