如何将锯齿状数组绑定到 DataGridView? [英] How to bind a jagged array into DataGridView?

问题描述

我有包含不同类型数据(整数、字符串、浮点数)的二维数组.

如何将其绑定到数据网格视图?

还是先转换成dataView或者BindingList或者DataTable再绑定到datagridview?

Object[,] 是完全动态的数据(行、列、数据类型不同.，如转储数据):(Excel 表格)

[0,x] "kjslwe" 3 "w" 45 "erer" 643 "reew" "54" 56 34

[1,y] 23 "e" 1 "sf" 123213 "ds" 343433

解决方案

您没有使用

在上面的例子中，我还设置了这些属性:

grid.AllowUserToAddRows = false;grid.AllowUserToDeleteRows = false;grid.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.AllCellsExceptHeader;

I have 2D array with different types of data(int, string, float).

How do i bind it to data grid view?

Or converting it to data View or BindingList or DataTable and then bind it to datagridview?

Edits: Object[,] is completely dynamic data(Different no of rows, columns, datatypes., Like dump data): (Excel sheets)

[0,x] "kjslwe" 3 "w" 45 "erer" 643 "reew" "54" 56 34

[1,y] 23 "e" 1 "sf" 123213 "ds" 343433

解决方案

You are not using a 2D Array, you are using a Jagged Array. A jagged array is an array whose elements are arrays. The elements of a jagged array can be of different dimensions and sizes. A jagged array is sometimes called an "array of arrays."

To show a jagged array in DataGridView, you can first calculate the number of columns which you need and set ColumnCount property of grid. Then add rows using an overload of Add method of Rows collection of grid which accepts param object[]. For example:

object[][] data = new object[][]{ 
        new object[] {"kjslwe", 3, "w", 45, "erer", 643, "reew", "54", 56, 34},
        new object [] {23, "e", 1, "so", 123213, "ds", 343433}
};

var columns = data.Max(x => x.Count());         /* Calculate number of columns */
grid.ColumnCount = columns;                     /* Set column count of grid   */
data.ToList().ForEach(x => grid.Rows.Add(x));   /* Add rows                    */

In the above example, I also set these properties:

grid.AllowUserToAddRows = false;
grid.AllowUserToDeleteRows = false;
grid.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.AllCellsExceptHeader;
