C# Double Assignment Guide

In C#, there are several ways to assign values to a double type.

1. Assign the value directly:
   double number = 3.14;
2. Assign the value of the expression to a double variable called result: 2.0 + 2.5.
3. casting:

   double value = (double)integer;

4. Parse the string using the Parse method:
   double value = double.Parse(“3.14”);
5. Parse the string using the TryParse method:
   double value;
   bool success = double.TryParse(“3.14”, out value);
   // If the parsing is successful, value will be assigned the parsed result and success will be true; otherwise, value will be 0 and success will be false.
6. Convert the data type using the Convert.ToDouble method:
   double result = Convert.ToDouble(“3.14”);

Above are several common ways to assign values to a double data type, choose the appropriate method based on your actual needs.
