CRR0049 - Environment.NewLine can be used

• Feb 28, 2025

This analyzer identifies “\r\n” string values which can be converted to Environment.NewLine to improve code readability and portability.

C#

public string MakeText(params string[] data) {
    string result = data[0];
    for (int i = 1; i < data.Length; i++)
        result += "\r\n" + data[i];
    return result;
}

VB.NET

Dim hello As String = "Hello World !!!" & "\r\n"

To fix the issue, convert the “\r\n” string value to Environment.NewLine:

C#

public string MakeText(params string[] data) {
    string result = data[0];
    for (int i = 1; i < data.Length; i++)
        result += Environment.NewLine + data[i];
    return result;
}

VB.NET

Dim hello As String = "Hello World !!!" & Environment.NewLine

Call the Use Environment.NewLine refactoring to replace the “\r\n” string with an Environment.NewLine property value.
