How do you append data to a field (SQL) using LINQ
I have an array that could go up to 308 values.
In the SQL table where this data is stored is a multi-line text box. So, the user in the web application can store any text. They useable stored the data like this.
Apple
Orange
Carrot
Here is the problem. I have been given a spreadsheet to update this particular <table> field with up to 308 values. I know that I can just move in the value to the variable and do submitchanges(); and that will work. However, I don't know how to do this with overwriting every value except the last in the field 308?
Thank you in advance.

foreach (Test d in match)
{
string[] StringArray = new string[5];
StringArray[0] = b.EpicInbasket1;
StringArray[1] = b.EpicInbasket2;
StringArray[2] = b.EpicInbasket3;
StringArray[3] = b.EpicInbasket4;
StringArray[4] = b.EpicInbasket5;
IEnumerable<string> result2 = from str in StringArray where str[0] != null select str;
foreach (string str in result2)
{
// HOW DO I APPEND THIS AND NOT OVERWRITE??
d.Message = (str);
// submit changes to the database.
tm.SubmitChanges();
}
}
Hi ,
I guess this is what you are after :
private void btnStringBuilderTest_Click (object sender, RoutedEventArgs e)
{
string[] StringArray = new string[5];
StringArray[0] = "Apple";
StringArray[1] = "Ball";
StringArray[2] = "Cat";
StringArray[3] = "Dog";
StringArray[4] = "Elephant";
IEnumerable<string> result2 = from str in StringArray select str;
System.Text.StringBuilder sb = new StringBuilder();
foreach (string str in result2)
{
sb.Append(str + "\n");
}
// MessageBox.Show(sb.ToStrin g());
tm.SubmitChanges();
}
If you don't want them on new line remove ' + "\n" '.
Byt, "from str in StringArray where select str" is more appropriate since your "where" clause always returns true.

Both of you provided the answer, but dd12 you provided the solution to my problem. I am new to LINQ, and I seriously did not want to write a stored procedure. I am going to accept dd12 answer because he actually went all the way and provided the solution.
ASKER
I don't know if this will need to go to the web master. However, dd12 went the extra step and finiished my logic. For that, thank you very much!!
I am learning LINQ and this one escaped me. I know how to do it in SQL, but I did not want to call on a stored procedure, when we have linq for C#.
Thanks again!!
