After using ReSharper, I feel quite helpful. However, after a while, I think the default "Code Cleanup" "Reformat Code" and "Full Cleanup" cannot meet my needs.
The main reason is that I don't want to use var, and both of them use var by default. So I figured out how to avoid var as much as possible. Even if var "Clean up" is available, I can remove var.
After research, we found that the settings were successful. First, right-click "Cleanup Code... ", then click the" Edit Profiles "button, and then click the Add button in the upper right corner to enter the name to set it, except for "Update file header" and "Embrace 'using' ctictives in region", the key is to set var, change the first item of Use 'var 'in declaration to "Can change 'var' to explicit type", and change the third item to "Use 'var' only when initializer has type usage.
