Purpose

This Refactoring replaces all references to a local variable with its initial value.

You may find a variable in your code whose value does not change and the meaning is trivial. If this variable is not commonly used, you can eliminate it by executing the Inline Temp Refactoring.

Availability

Available when the cursor is on a local variable declaration or reference assuming the variable does not change.

Usage

1. Place the caret on a local variable whose value does not change.

   Note

   The blinking cursor shows the caret’s position at which the Refactoring is available.

   C#

   float CalculateDiscount(float price) {
       int percentage = GetCurrentDiscount();
       float fraction = (float)percentage / 100;
       return price - │fraction * price;
   }
   

   VB.NET

   Private Function CalculateDiscount(ByVal price As Single) As Single
       Dim percentage As Integer = GetCurrentDiscount()
       Dim fraction As Single = CSng(percentage) / 100
       Return price - │fraction * price
   End Function
   

2. Press the Ctrl + . or Ctrl + ~ shortcut to invoke the Code Actions menu.
3. Select Inline Temp from the menu.

After execution, the Refactoring replaces the variable references with its initial value and removes the initialization.

C#

float CalculateDiscount(float price) {
    int percentage = GetCurrentDiscount();
    return price - (float)percentage / 100 * price;
}

VB.NET

Private Function CalculateDiscount(ByVal price As Single) As Single
    Dim percentage As Integer = GetCurrentDiscount()
    Return price - CSng(percentage) / 100 * price
End Function
