C# 读取文件并动态创建文本框

创建汽车类

namespace A3_Reese
{

    public partial class Form1 : Form
    {

创建一个名为CarsInfo的类来存储我需要的值 内部类CarsInfo { 私人字符串卡马克； 私人字符串卡莫德尔； 私人国际年； 私人双里程

                String[] carPieces = inputLine.Split(' ');

                int year = int.Parse(carPieces[0]);
                double mileage = double.Parse(carPieces[1]);
                String carMake = carPieces[2];
                String carModel = carPieces[3];


                cars.Add(new CarsInfo(carMake, carModel, year, mileage));

                inputLine = FileIn.ReadLine();

            }
            FileIn.Close();
        }
    }

如果要将文件中的数据遍历到表单，可以使用

for

语句，并根据索引获取相应的值。此外，要访问列表“cars”中的项目，需要定义一些

属性

        public CarsInfo(string carMake, string carModel, int year, double mileage)
        {
            this.carMake = carMake;
            this.carModel = carModel;
            this.year = year;
            this.mileage = mileage;

        }


    }
}

现在，假设您已经完成了文件读取，您可以参考下面的代码来动态创建控件

class CarsInfo
{
    string carMake;
    string carModel;
    int year;
    double mileage;
    public string CarMake { get { return carMake; } }
    public string CarModel { get { return carModel; } }
    public int Year { get { return year; } }
    public double Mileage { get { return mileage; } }
}

List cars=new List{new CarsInfo（“C1”、“M1”、2,1000.3）、new CarsInfo（“C2”、“M2”、5,7654.34）、new CarsInfo（“C3”、“M3”、3,3225”）；
对于（int i=0；i
为什么要发布designer.cs文件？您应该向我们展示您为解决问题而编写的代码听起来像是网格作业。或者是用户控件。或者是网格。嘿，伙计们，我完全发布了错误的代码部分。对此我很抱歉，谢谢您帮助我更正它
                String[] carPieces = inputLine.Split(' ');

                int year = int.Parse(carPieces[0]);

                String carMake = carPieces[2];
                String carModel = carPieces[3];


                cars.Add(new CarsInfo(carMake, carModel, year, mileage));

                inputLine = FileIn.ReadLine();

            }
            FileIn.Close();
        }
    }

        public CarsInfo(string carMake, string carModel, int year, double mileage)
        {
            this.carMake = carMake;
            this.carModel = carModel;
            this.year = year;
            this.mileage = mileage;

        }


    }
}
