Question

我有2个对象数组。我需要将其中一个对象值添加到名称匹配的第二个数组中。使用最少的代码执行此操作的最有效方法是什么？

firstArray = [
              {name: "Henry", balance: 2176.90, Age: 26},
              {name: "Jon", balance: 122.10, Age: 31},
              {name: "Dave", balance: 258.23, Age: 42},
              {name: "Tom", balance: 591.00, Age: 19},
              {name: "Mary", balance: 12.54, Age: 56},
              {name: "Rick", balance: 5287.25, Age: 29},
              {name: "Jane", balance: 6527.20, Age: 24}
           ]

secondArray = [
              {user: "Henry", city: "New York", dept: "Sales"},
              {user: "Vanessa", city: "New York", dept: "Sales"},
              {user: "Susan", city: "Dallas", dept: "Marketing"},
              {user: "Jon", city: "New York", dept: "Management"},
              {user: "Dave", city: "Dallas", dept: "Marketing"}
              {user: "Jay", city: "Spokane", dept: "IT"}
           ]

secondArray = [
              {user: "Henry", city: "New York", dept: "Sales", balance: 2176.90},
              {user: "Vanessa", city: "New York", dept: "Sales", balance: "N/A"},
              {user: "Susan", city: "Dallas", dept: "Marketing", balance: "N/A"},
              {user: "Jon", city: "New York", dept: "Management", balance: 122.10},
              {user: "Dave", city: "Dallas", dept: "Marketing", balance: 258.23}
              {user: "Jay", city: "Spokane", dept: "IT", balance: 591.00}
           ]

你需要遍历数组，没有更有效的方法来处理它。

        private void button1_Click(object sender, EventArgs e)
    {

        DataGridViewImageColumn imageColumn = new DataGridViewImageColumn();
        DataGridViewImageCell imageCell = new DataGridViewImageCell();
        Bitmap bmpImage = null;


        int number_of_rows = dgv_resultats.RowCount;
        for (int i = 0; i < number_of_rows-1; i++)
        {

            //bmpImage = (Bitmap)Image.FromFile(Application.StartupPath + dgv_resultats.Rows[1].Cells[1].Value.ToString(), true);

            bmpImage = (Bitmap)Image.FromFile(@"D:\LigueStats\Data\Logo\Ligue 1\EST.png", true);
            imageColumn.Image = bmpImage;

            imageColumn.ImageLayout = DataGridViewImageCellLayout.Stretch;

            dgv_resultats.Rows[i].Cells["logo_dom"].Value = bmpImage;



        }



    }

组合或添加具有共同值的数组
