Error : Meta data is not found

I got this error when I was working with Dev Express Reporting Tool. I investigated why I am getting this run time error.

Then I came to know that actually corresponding dll is missing. I checked on Application Reference list and GAC list for the dll for which meta data is not found.

I surprisingly notice targeted dll was both place. Then why I am missing the dll? To solve the problem, I simply set copy to local to true.

I got the problem fixed. Aha great release! I am very glad to share my experience in my blog.

System.Text.StringBuilder sb = new System.Text.StringBuilder("Rat: the ideal pet");
sb.Append(" is caught");
sb[0] = 'C';
Output : Cat: the ideal pet is caught

Expression evaluation in C#

Try with this code block which is faster than using codeDom
static double Evaluate(string expression)
var loDataTable = new DataTable();
var loDataColumn = new DataColumn("Eval", typeof(double), expression);
return (double)(loDataTable.Rows[0]["Eval"]);
