在C#中，可以使用SQL Server的BACKUP DATABASE语句来备份数据库中的表。以下是一个示例代码：
using System;
using System.Data.SqlClient;
class Program
{
static void Main()
{
string connectionString = "your_connection_string_here";
string tableName = "your_table_name_here";
string backupPath = "your_backup_path_here";
using (SqlConnection connection = new SqlConnection(connectionString))
{
connection.Open();
string query = $"BACKUP DATABASE [YourDatabaseName] TABLE {tableName} TO DISK = '{backupPath}'";
SqlCommand command = new SqlCommand(query, connection);
command.ExecuteNonQuery();
Console.WriteLine("Table backup complete.");
}
}
}
请注意，需要将代码中的your_connection_string_here替换为您的数据库连接字符串，your_table_name_here替换为您要备份的表名，your_backup_path_here替换为备份文件的路径。此代码将执行一个SQL命令来备份指定的表到指定的文件路径。
