How Do I Convert This Code Into Linq In C#

string readAllDataFromFile = sr.ReadToEnd();
                   sr.Close();
                   fs.Close();
                   string[] SplitAllData = readAllDataFromFile.Split('\r');
                   foreach (string para in SplitAllData)
                    {
                        string[] temp = para.Trim('\n').Split('~');

                        if (temp[0] == "ShowMsgBoxInGUI" && (temp[1] == "True"||temp[1]=="Y"))
                        {
                            ShowMsgBoxInGUI = true;
                        }

                        if (temp[0] == "FAPNotFoundForLine" && (temp[1] == "S" ||temp[1]=="Y"))
                        {
                             FAPNotFoundForLine = "S";
                        }

                        if (temp[0] == "XMLRelatedMsgBox" && (temp[1] == "T"||temp[1]=="Y"))
                        {
                            XMLRelatedMsgBox = true;
                        }

                        if (temp[0] == "RegAndTmplInLog" && (temp[1] == "True"||temp[1]=="Y"))
                        {
                            RegAndTmplInLog = true;
                        }

                    }
                    sr.Close();
