The **C# string format** is used to modify a string. It does so by inserting objects and variables at desired positions.

# Syntax
```
String.Format("anyString {index[,alignment][:formatString]}", object);
```

**`anyString`:** It is an optional string.

**`index`:** The position where an object or a variable can be inserted (it always starts with zero). In the case of NULL, an empty string is inserted.

**`alignment`:** It is an optional, signed integer used to align a string to the left or right.

**`formatString`:** It is also optional; the complete formatting types can be found [here](https://docs.microsoft.com/en-us/dotnet/standard/base-types/formatting-types?view=netframework-4.7.2).

class Marvel
{
    static void Main()
    {
      string str = "Marvel Characters: {0}, {1}";
      string tempStr = string.Format(str, "Thor", "Deadpool");
      System.Console.WriteLine(tempStr);
    }
}

>You can try different alignments and formatting for *date*, *money*, and *custom* formats as well.
