在Visual Studio中使用C#实现Access数据库的插入、更新和删除操作可以通过ADO.NET来实现。ADO.NET是.NET Framework中用于访问数据的一组类和API。
首先,需要在Visual Studio中创建一个C#项目,并引入System.Data.OleDb命名空间,该命名空间包含了访问Access数据库所需的类和方法。
using System.Data.OleDb;
string connectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\\path\\to\\database.accdb";
string insertQuery = "INSERT INTO TableName (Column1, Column2) VALUES (@Value1, @Value2)";
using (OleDbConnection connection = new OleDbConnection(connectionString))
{
connection.Open();
using (OleDbCommand command = new OleDbCommand(insertQuery, connection))
{
command.Parameters.AddWithValue("@Value1", value1);
command.Parameters.AddWithValue("@Value2", value2);
command.ExecuteNonQuery();
}
}
using System.Data.OleDb;
string connectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\\path\\to\\database.accdb";
string updateQuery = "UPDATE TableName SET Column1 = @Value1, Column2 = @Value2 WHERE ID = @ID";
using (OleDbConnection connection = new OleDbConnection(connectionString))
{
connection.Open();
using (OleDbCommand command = new OleDbCommand(updateQuery, connection))
{
command.Parameters.AddWithValue("@Value1", newValue1);
command.Parameters.AddWithValue("@Value2", newValue2);
command.Parameters.AddWithValue("@ID", recordID);
command.ExecuteNonQuery();
}
}
using System.Data.OleDb;
string connectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\\path\\to\\database.accdb";
string deleteQuery = "DELETE FROM TableName WHERE ID = @ID";
using (OleDbConnection connection = new OleDbConnection(connectionString))
{
connection.Open();
using (OleDbCommand command = new OleDbCommand(deleteQuery, connection))
{
command.Parameters.AddWithValue("@ID", recordID);
command.ExecuteNonQuery();
}
}
以上代码中的"TableName"是要操作的表名,"Column1"、"Column2"是表中的列名,"@Value1"、"@Value2"、"@ID"是参数名,可以根据实际情况进行修改。
