C# Convert Class

In C#, the Convert class is an utility class which is a part of the .NET Framework and provides methods to convert one data type to another. It's a static class, meaning you don't need to create an instance of it to use its methods.

The primary purpose of the Convert class is to facilitate the conversion of various data types, such as converting a string to an integer, a double to a string, or any other supported data type conversion. This is particularly useful when working with different data types and you need to ensure compatibility or perform specific operations that require data in a particular format.

Here are some common use cases for the Convert class:

1. String to Other Types and Vice Versa:

   string str = "123";
   int intValue = Convert.ToInt32(str);

   double doubleValue = 10.5;
   string doubleStr = Convert.ToString(doubleValue);

2. Boolean Conversions:

   string boolStr = "True";
   bool boolValue = Convert.ToBoolean(boolStr);

3. DateTime Conversions:

   string dateStr = "2023-10-05";
   DateTime dateValue = Convert.ToDateTime(dateStr);

4. Null Handling: The Convert class can handle null values and return a specified default value if the input is null.

   string nullString = null;
   int defaultValue = 10;
   int result = Convert.ToInt32(nullString) ?? defaultValue;

5. Conversions between Numeric Types:

   double doubleValue = 10.5;
   int intValue = Convert.ToInt32(doubleValue);

It's important to note that using Convert can throw exceptions if the conversion is not possible (e.g., trying to convert a non-numeric string to an integer), so it's a good practice to handle exceptions appropriately in your code when using Convert methods.
