The designer cannot process the code at line

Posted by codingsense on December 5, 2010

From somedays back I was getting a weird problem while opening the design of windows form. The error message looked like the below one

The designer cannot process the code at line 37: this.comboBox1.Items.AddRange(new []{ “one”, “two”, “three”, “four”}); The code within the method ‘InitializeComponent’ is generated by the designer and should not be manually modified. Please remove any changes and try opening the designer again.

If I commented the AddRange line it was working fine or It was pointing at the next line those had AddRange method. I quickly googled for the solution and found many but none of the fix was useful. By careful observation I found that something was missing the line. See if you can observe what’s missing the below line 😉

 this.comboBox1.Items.AddRange(new []{

Just adding the type of the array that I was creating solved my problem, for above problem I added new object[] and then all worked fine.

this.comboBox1.Items.AddRange(new object[]{

After fixing the issue I started searching for the person who had removed it, I wanted to show him the issue so that he will not do the same next time. After searching for hours I found that it was Mr. ReSharper who had removed the type. From then I started carefully using Resharper instead of just clicking on what it suggests.

Happy coding 🙂

      Hi Anand,

      Are you getting the same error that I have mentioned?
      Check the error, is it taking you to the AddRange line when clicked on show code?? What other tools are installed as plugin for your Visual studio??
