Save

[martialdc]

I have tried this code to save records in C#.NET.

//Save
DataRow row = dataSet11.Student.NewStudentRow;
row.ItemArray(0) = textBox1.Text;
row.ItemArray(1) = textBox2.Text;
row.ItemArray(2) = textBox3.Text;
row.ItemArray(3) = textBox4.Text;
dataSet11.Student.AddStudentRow;
dataSet11.AcceptChanges;

But it doesn't work.
Any solution to this problem?

Try using the 'Update' method of the dataAdapter object. 'AcceptChanges' tells the dataSet to reset its dirty flags.

Do you come from VB?

You need function parentheses even for argument-less functions:
dataSet11.AcceptChanges();

Also array indexing is done using brackets:
row.ItemArray[0]

or ItemArray might even be the indexer (look it up in the reference):
row[0]
