I have created a list in c#, now I need to insert the list into SQL Server 2008. Is this possible? please explain with a simple example.
推荐答案
这是一个简单的例子:
List<String> list = new List<String>() { "A", "B", "C" };
using (var con = new SqlConnection(connectionString))
{
con.Open();
using (var cmd = new SqlCommand("INSERT INTO TABLE(Column)VALUES(@Column)", con))
{
cmd.Parameters.Add("@Column", SqlDbType.VarChar);
foreach (var value in list)
{
cmd.Parameters["@Column"].Value = value;
int rowsAffected = cmd.ExecuteNonQuery();
}
}
}
这只是遍历列表中的所有项目并使用 ExecuteNonQuery.
This just loops through all items in the list and executes one insert-command after the other with ExecuteNonQuery.
