QuestionC# How to use place holder in string variable Pin

MemberMou_kol18-Nov-21 5:34 
see the code how i am creating place holder now. _Yoy has a formula used in excel.
C#
private string _Yoy = @"IF(AND(ISNUMBER(C#),P#>0,NOT(ISERROR(C#/P#))),C#/P#-1,"""")";
             public  string YoY
             {
                 get { return _Yoy; }
                 set { _Yoy = value; }
             }
        
             private void button1_Click(object sender, EventArgs e)
             {
                string strBMFormula = YoY.Replace("P#", "2005.13").Replace("C#", "7777.10");
             }



I am replacing P# & C# with some value at runtime and program working as expected but i am doing this in large loop where Replace() function is getting called repeatedly which may increase memory use.

C#
@"IF(AND(ISNUMBER(C#),P#>0,NOT(ISERROR(C#/P#))),C#/P#-1,"""")";

here i gave 4 double quote because there would two double quote in excel function.

i am using .Net version 4.5

so please suggest me how to create a place holder in string variable and put my value there without using Replace function.

i try this approach too but still no luck.
C#
private void button1_Click(object sender, EventArgs e)
 {
     string strBMFormula = Replacement("A10", "Z210");
 }
    
 private string Replacement(string value1, string value2)
 {
     return @"IF(AND(ISNUMBER({value1}),{value2}>0,NOT(ISERROR({value1}/{value2}))),{value1}/{value2}-1,"""")";
 }
