问题描述

                      OleDbConnection con = new OleDbConnection();
           con.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0; Data Source=" + Application.StartupPath + "\\kodmatikdatabase.accdb";

con.Open();
           OleDbCommand sorgu = new OleDbCommand(("insert into geneltablo (KodAdi,Aciklama,GirisTarihi,Link,ProgramlamaDili,Puan,Durum) values (@KodAdi,@Aciklama,@GirisTarihi,@Link,@ProgramlamaDili,@Puan,@Durum)"),con);
           sorgu.Parameters.AddWithValue("@KodAdi", textBox1.Text);
           sorgu.Parameters.AddWithValue("@Aciklama", richTextBox1.Text);
           sorgu.Parameters.AddWithValue("@GirisTarihi", dateTimePicker1.Text);
           sorgu.Parameters.AddWithValue("@Link", textBox2.Text);
           sorgu.Parameters.AddWithValue("@ProgramlamaDili", comboBox1.Text);
           sorgu.Parameters.AddWithValue("@Puan", comboBox3.Text);
           sorgu.Parameters.AddWithValue("@Durum", comboBox2.Text);


           sorgu.ExecuteNonQuery();

当我按下按钮

"sorgu.ExecuteNonQuery();"在这一行

总是给我这个错误

条件表达式中的数据类型不匹配."

怎么了 ? :confused :: confused :: confused:

when i push button

" sorgu.ExecuteNonQuery(); " in this line

always give me this error

"Data type mismatch in criteria expression."

What is wrong ? :confused::confused::confused:
