C# | String.ToUpperInvariant Method
String.ToUpperInvariant Method is used to get a copy of this String object converted to uppercase using the casing rules of the invariant culture. Here “invariant culture” represents a culture that is culture-insensitive.
public string ToUpperInvariant ();
Return Value: The return type of this method is System.String. This method will return a string which is the uppercase equivalent of the current string.
Below given are some examples to understand the implementation in a better way:
String before ToUpperInvariant: WelCome tO GeeKSfOrGeeKs String after ToUpperInvariant: WELCOME TO GEEKSFORGEEKS
string 1: GEeks string 2: GEEKS string 1: geeks string 2: GEEKS string 1: GEEKS string 2: GEEKS
- The invariant culture represents a culture that is culture-insensitive. It is associated with the English language but not with a specific country or region.
- ToUpperInvariant() method does not modify the value of the current instance. Instead, it returns a new string in which all characters in the current instance are converted to uppercase.
- This method can’t be overloaded if you try to overload this method, it will give you compile time error.
