cshap将world写入sqlserver

以下是C#代码示例，将字符串"world"插入到名为"mytable"的SQL Server数据库表中的"mycolumn"列中：

using System.Data.SqlClient;

string connectionString = "Data Source=myServerAddress;Initial Catalog=myDataBase;User ID=myUsername;Password=myPassword";
string insertQuery = "INSERT INTO mytable (mycolumn) VALUES (@value)";

using (SqlConnection connection = new SqlConnection(connectionString))
{
    SqlCommand command = new SqlCommand(insertQuery, connection);
    command.Parameters.AddWithValue("@value", "world");

    try
    {
        connection.Open();
        int rowsAffected = command.ExecuteNonQuery();
        Console.WriteLine("Rows Affected: " + rowsAffected);
    }
    catch (Exception ex)
    {
        Console.WriteLine(ex.Message);
    }
}

请注意，您需要使用与您的SQL Server实例匹配的正确连接字符串，并根据需要更改表名和列名。此外，使用参数化查询可以帮助防止SQL注入攻击。
