Code inspection: String formatting method problems

This inspection verifies that format items in the format argument of the String.Format and similar methods are used correctly.

If you have a custom formatting method that behaves like String.Format, you can mark it with the [StringFormatMethodAttribute] from JetBrains.Annotations to enable the corresponding checks. Here is an example:

        
[StringFormatMethod("message")]
void ShowError( string message, params object[] args)
{
    // Show error
}

void Test()
{
    // Warning: Non-existing argument in format string
    ShowError("Failed: {0}");
}
