efStudent.sponsor = Convert.ToString(student.Sponsor);
My problem is that I can't convert the efStudent.sponsor which is a string to student.Sponsor, because it is a string[].
I need some help to convert it from string to string[].
To convert a string to string[], you can initialize a single-element array:
efStudent.sponsor = new string[] { Convert.ToString(student.Sponsor) };

var data = #"{
""owner1"":""Name"",
}";
Need to add variable in the above object in c#
If your data is json string, you can modify it by JObject like this:
var jsonData = JObject.Parse(data);
jsonData["owner1"] = "owner1";
jsonData["owner2"] = "owner2";

I'm new to C#.
I have a method that returns an object with the List of objects inside.
0 {{DapperRow, RecordedFormID = 'id1'}} object {Dapper.SqlMapper.DapperRow}
1 {{DapperRow, RecordedFormID = 'id2'}} object {Dapper.SqlMapper.DapperRow}
How can I get those ids as strings?
Here is a screenshot
You can use System.Linq namespace and do this:
yourObject.Select(x => x.RecordedFormID);

I have a List as following
List<string> email = File.ReadAllLines(fileName).ToList<string>();
filename is text I openFileDialog. The text in file txt is 3 line with 3 gmail
I want convert List to
string[] arRcpt = new string[] { };
The File.ReadAllLines(fileName) returns a string[]. You don't need to convert it into a list and then to string[]. You can directly assign it to an array.
string[] arRcpt = File.ReadAllLines(fileName)

public class itemObject { public string items; }
values - item = "name1,name2" or items = "item3"
Need linq to split by ',' if exists else one string array.
This doesnt require linq, its the default behaviour of String.Split
var array = items.Split(',');

I had error "cannot convert string[] to string"
string[] digitsArray = {dd, pp, ff, cc};
As digitsArray array of arrays and all "dd, pp, ff, cc" are arrays have string values
I think you want
string[][] digitsArray = {dd, pp, ff, cc};
As if you haven't been given enough solutions already - a LINQ version:
var digitsArray = new[]{dd, pp, ff, cc}.SelectMany(foo=>foo).ToArray();
If you want one-dimensional array - you can use Enumerable.Concat and Enumerable.ToArray:
string[] digitsArray = dd.Concat(pp).Concat(ff).Concat(cc).ToArray();
