C＃错误：无法将类型'string'隐式转换为'System.Windows.Forms.Control'（CS0029）

Question

i am currently writing a program that allows users to view multiple transparent images ontop of one another, they are able to toggle 6 different images on or off.

To explain how it works:

Image 1 is always the background (unless its toggled off in which case the next 'on' image is the background)

for example:

• if image 1 is ON and image 2 is ON then image 2 uses image 1 as its parent.

• if image 1 is ON, image 2 is OFF and image 3 is ON then image 3 will use Image 1 as its parent

etc

To achieve this i created an array - imageName[6]. When an image is turned on the corresponding element (eg image 1 = imageName[0]) says [image1].

Using this method i was hoping to create a control which would change the 'parent' of an image based on the example shown above.

I thought using the following code would work:

imageB.parent = imageName[0]

//This is just an example, the required answer would be imageB.parent = imageA //I need to achieve this answer using the data in the array.

but i just get the error message listed in the title:

(Cannot implicitly convert type 'string' to 'System.Windows.Forms.Control' (CS0029) )

Could anyone help me with this problem? Im afraid im stumped.

Please note, my code is alot more complicated then this, the above just shows a small snippet of it rather then displaying all 776 lines of my code xD

UPDATE: To summarise, i need to assign an images parent based on the name stored in part of my array (in this case [0] ie [image1]

The error im having makes this impossible,

Is there a way to solve this or am i just writing very bad code?

Answer 1

You have a string which is factionLayersID[0] and you are trying to assing it a Control variable.That's why you are getting that exception.

Your array elements type should be Control . Like this:

Control[] factionLayers = new Control[6];

Then you can assign your element to parent control:

imageB.parent = factionLayers[0]
