CRR0052 - String interpolation can be used

Feb 28, 2025

This analyzer identifies composed string expressions which can be converted to interpolated strings. Interpolated strings are easier to read than formatted strings.

C#
VB.NET

csharp

return "Found record at the position " + i;

Return "Found record at the position " & i

To fix this issue, use the interpolated string instead of the composed string expression.

C#
VB.NET

csharp

return $"Found record at the position {i}";

Return $"Found record at the position {i}"

Call the Convert to String Interpolation refactoring to replace the composed string with an interpolated string. To do it in different places at once, use the Code Cleanup feature with the Convert to String Interpolation rule enabled.
