Question

I have a model:

public class KPIResults
{
   public virtual string Title { get; set; }
   public virtual int Total { get; set; }
   public virtual  int Week6 { get; set; }
   public virtual  int Week5 { get; set; }
   public virtual  int Week4 { get; set; }
   public virtual  int Week3 { get; set; }
   public virtual  int Week2 { get; set; }
   public virtual  int Week1 { get; set; }

   public virtual string stringWeek6 { get; set; }
   public virtual string stringWeek5 { get; set; }
   public virtual string stringWeek4 { get; set; }
   public virtual string stringWeek3 { get; set; }
   public virtual string stringWeek2 { get; set; }
   public virtual string stringWeek1 { get; set; }
}

In my reporting repository i have:

 int strfound = 0;
 string str = "Number";
 foreach (DataRow dr in dt.Rows)
 {
    string title = dr["Title"].ToString();
    int total = Convert.ToInt32(dr["Total"]);
    if (dr["Week6"].contains("Number")  //synntacs not right?
        var week6 = dr["strWeek6"]
    end

    or do this:
    strfound = str.IndexOf(dr);  //syntacs not right?
    if (strfound == 0)
    {
         var week6 = dr["strWeek6"]
    } 
    var week6 = Convert.ToInt32(dr["Week6"]);
    var week5 = Convert.ToInt32(dr["Week5"]);
    var week4 = Convert.ToInt32(dr["Week4"]);
    var week3 = Convert.ToInt32(dr["Week3"]);
    var week2 = Convert.ToInt32(dr["Week2"]);
    var week1 = Convert.ToInt32(dr["Week1"]);

    results.Add(new KPIResults() {Title = title, Total = total, Week6 = week6, Week5 = week5, Week4 = week4, Week3 = week3, Week2 = week2, Week1 = week1});

  }
  return results;

I should maybe try and do a string search but my code in the is is not right. I search for ways to handle string but not clear.

thanks

Somewhat unclear on what you are trying to do, to answer your question, All I want to know is it possible to cast the var type to be stored as an int or the other way around? No.

I think your best bet would be to use string then it will be able to hold text and numbers. You could do a regex test to check if it contains text, then if not, convert the number it stores to an int for you to work this.

Or just make a better model that will include all the sections you need.

You could also use .GetType() to return the type of var.

Update

Ok, it looks like you are now trying to detect if dr["Week6"] contains a string or an int. One way to go about this is:

int number;
if(int.TryParse(dr["Week6"], out number))
    var week6 = dr["strWeek6"]

If dr["Week6"] can be converted into an int, then the if statement is true and number will contain the value of dr["Week6"].

Here is the metadata for int.TryParse:

Summary:
Converts the string representation of a number to its 32-bit signed integer
equivalent. A return value indicates whether the conversion succeeded.

Parameters: s:
A string containing a number to convert.

result:
When this method returns, contains the 32-bit signed integer value equivalent
to the number contained in s, if the conversion succeeded, or zero if the
conversion failed. The conversion fails if the s parameter is null, is not
of the correct format, or represents a number less than System.Int32.MinValue
or greater than System.Int32.MaxValue. This parameter is passed uninitialized.

Returns:
true if s was converted successfully; otherwise, false.
