Question

很抱歉重复发布相同类型的问题，但我非常困惑

场景：我有一个数据表，可以动态地将数据填充到数据网格/运行时间，如下所示：

dt.Rows.Add(value1, value2, value3, value4, value5, value6, value6, value7, value8);

现在我在app.config文件中有数据，我检索如下所示：

// app.config file contains string with comma separated and I am splitting it in code

string num1 = ConfigurationManager.AppSettings["crNum"];
string[] values = num1 .Split(',');

foreach (string crNum in values)
{
    // I need code here to delete the entire rows where value1 == crNum 
    // in my above data table dt and also when I reopen/refresh 
    // my c# application I should not see the row deleted before.
}

最后我将数据表插入网格

myCRGrid.DataSource = dt;

我是C＃的新手，我为这样一个奇怪的问题道歉。

请帮忙

谢谢！

试试这个

#include "Ball.h"
#include "Team.h"
#include "Player.h"

extern vector<Player> team;

Ball::Ball()
:   X_ball(2),
    Y_ball(5)
{
    current = NULL;
    previous = NULL;

}

void Ball::assign(){
    //vector<Player> team;
    int x;
    int y;
    x=(team[0].getX())-X_ball;
    y=(team[0].getY())-Y_ball;
    int min=x+y;
    int k=0;
    for (int i=1; i<team.size(); i++){
        x=(team[i].getX())-X_ball;
        y=(team[i].getY())-Y_ball;
        int sum=x+y;
        if(sum<min){
            k=i;
        }
    }
    current = &team[k];
}

DataTable过滤器使用app.config和c＃app中的数据
