Conflict warning after rename the form

In my first project, I encountered this warning many times. After reading the warning description, I don't know exactl开发者_运维知识库y what it is and how to fix it. I think it occurs when I change the name of winform(.cs file). Please let me know what is the cause of this warning and how to fix it? Thanks for your help.

Warning 1 The type 'Patience_Management.med' in 'C:\Users\TNhan\documents\visual studio 2010\Projects\Patience_Management\Patience_Management\Class1.cs' conflicts with the imported type 'Patience_Management.med' in 'c:\Users\TNhan\Documents\Visual Studio 2010\Projects\Patience_Management\Patience_Management\bin\Debug\Patience_Management.exe'.

Looks like you have two types with the same name. Rename one of them, clean the solution, and rebuild.

I'm not 100% sure this will fix the problem, but you should not use the same name for an object instance as the name of the object itself. In your screenshot, you're using:

addPatience addPatience = new addPatience(TextBox1.Text);

as well as

kham kham = new kham // rest of line ommitted

Without trying it myself, I'm not sure that would even compile, and if it did you might have run-time issues. At the very least, it would be confusing to read for any developer that would have to maintain your code.

Remember, C# is case-sensitive.
