Look into Reflection, it'll let you do what you want. However, in the end, the code will probably be about as complex as your select code.

it is possible, by using reflection.

<pre><code>Dim thisType As Type = Me.GetType()
Dim theMethod As Reflection.MethodInfo = thisType.GetMethod("col" &amp; strColour, Reflection.BindingFlags.NonPublic Or Reflection.BindingFlags.Instance)

If Not theMethod Is Nothing Then
 'this, if you have parameters
 theMethod.Invoke(Me, New Object() { add your parameters here, if any })
 'this, if you don't have parameters
 theMethod.Invoke(Me)
End If

blocks|key|3236725|text|我会使用select+case，除非你有非常多的颜色，或者更好地将这些方法重构为一个方法。如果有必要的话，也许是一个通用的。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3236726|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I would use a select case unless you have a very large number of colours, or even better refactor those methods into 1 method. perhaps a generic one if necessary.

blocks|key|3236749|text|如果没有重写颜色处理子例程的方法，那么就没有好的方法可以这样做。您的选项：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3236750|3236751|Reflection，，它允许您获取对象成员(方法和属性)的名称。如果你的例程是在一个对象上，你可以使用这个。|ordered-list-item|offset|length|3236752|信不信由你，最好有一个大的select语句！它看起来不美观，但性能比使用反射要好得多。|style|BOLD|3236753|3236754|entityMap|0|LINK|mutability|MUTABLE|url|http://markbeaton.com/SoftwareInfo.aspx?ID=81a0ecd0-c41c-48da-8a39-f10c8aa3f931^0|0|0|0|A|0|0|B|A|0|0^^$0|@$1|2|3|4|5|6|7|U|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|V|8|@]|9|@]|A|$]]|$1|C|3|D|5|E|7|W|8|@]|9|@$F|X|G|Y|1|Z]]|A|$]]|$1|H|3|I|5|E|7|10|8|@$F|11|G|12|J|K]]|9|@]|A|$]]|$1|L|3|-4|5|6|7|13|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|14|8|@]|9|@]|A|$]]]|N|$O|$5|P|Q|R|A|$S|T]]]]

If there is no way to rewrite the color-handling sub-routines, then there is no good way to do it. You options:

<li><a href="http://markbeaton.com/SoftwareInfo.aspx?ID=81a0ecd0-c41c-48da-8a39-f10c8aa3f931" rel="nofollow noreferrer">Reflection</a>, which allows you to get the names of objects members (methods and properties). If your routines are on an object you can use this.</li>
<li>Believe it or not, it is probably better to have a big select statement! It looks inelegant, but will perform much better than using reflection.</li>

Is there a way to call a procedure in Visual Basic (.net) with a variable name?

For example, the variable strColour can be one of 10 pre-defined values, green blue black white red pink orange yellow indigo purple. How to handle each one is in it's own Sub Routine, colgreen, colblue, colblack and so on.

I can use a bunch of if..then..else and select case, but what I'd like to have is something like VBA Excel's Run "col" &amp; strColour

Is it possible?

有没有办法在Visual Basic (.net)中用变量名调用过程？例如，变量strColour可以是10个预定义的值之一:绿色、蓝色、黑色、白色、红色、粉色、橙色、黄色、蓝色、紫色。如何处理每一个都在它自己的Sub例程中，colgreen，colblue，colblack等等。我可以使用大量的if..then..e...
