C#实现对二维数组排序的方法实现对二维数组排序的方法

主要介绍了C#实现对二维数组排序的方法,实例分析了C#数组遍历与排序的相关技巧,需要的朋友可以参考下

本文实例讲述了C#实现对二维数组排序的方法。分享给大家供大家参考。具体实现方法如下：

/// <summary>

/// A generic routine to sort a two dimensional array of a specified type based on the specified column.

/// </summary>

/// <param name="array">The array to sort.</param>

/// <param name="sortCol">The index of the column to sort.</param>

int colCount = array.GetLength(1), rowCount = array.GetLength(0);

if (sortCol >= colCount || sortCol < 0)

throw new System.ArgumentOutOfRangeException("sortCol", "The column to sort on must be contained within the array bounds.");

DataTable dt = new DataTable();

// Name the columns with the second dimension index values, e.g., "0", "1", etc.

for (int col = 0; col < colCount; col++)

{

DataColumn dc = new DataColumn(col.ToString(), typeof(T));

dt.Columns.Add(dc);

}

dt.Rows.Add(rowData);

}

// Sort by using the column index = name + an optional order:

DataRow[] rows = dt.Select("", sortCol.ToString() + " " + order);

for (int row = 0; row <= rows.GetUpperBound(0); row++)

{

DataRow dr = rows[row];

for (int col = 0; col < colCount; col++)

{

array[row, col] = (T)dr[col];
