我创建了一系列列表。该阵列有七行代表星期几,列表包含医生预约的可用插槽。我试图用GridView
或DataList
(任何更合适的方式)绑定它而没有成功。
我已经宣布了名单:
List<string>[] list=new List<string>[7]; //An array of 7 lists
for (int i = 0; i < 7; i++)
{
list[i]=new List<string>();
}
我已经用字符串填写了列表,这些字符串代表了医生预约的可用位置。
我希望实现的结果是其中一位医生的可用性,如本网站所示:link

您可以将数组更改为List<List<string>>
,如下所示:
List<List<string>> list = new List<List<string>>();
然后您可以通过以下方式将其绑定到GridView
(仅适应您的情况):
protected void Page_Load(object sender, EventArgs e)
{
List<string> cols = GetColDefsFromBackend();
List<List<string>> rows = GetDataFromBackend();
GridView1.DataSource = CreateDataTable(cols, rows);
GridView1.DataBind();
}
private System.Data.DataTable CreateDataTable(List<string> columnDefinitions, List<List<string>> rows)
{
DataTable table = new DataTable();
foreach (string colDef in columnDefinitions)
{
DataColumn column;
column = new DataColumn();
column.DataType = typeof(string);
column.ColumnName = colDef;
table.Columns.Add(column);
}
// Create DataRow and Add it to table
foreach (List<string> rowData in rows)
{
DataRow row = table.NewRow();
// rowData is in same order as columnDefinitions
for (int i = 0; i < rowData.Count; i++)
{
row[i] = rowData[i];
}
table.Rows.Add(row);
}
return table;
}
/// <summary>
/// Simulates a StoredProcedureCall which returns
/// the data in a List with Lists of strings
/// </summary>
private List<List<string>> GetDataFromBackend()
{
List<List<string>> myData = new List<List<string>>();
myData.Add(Row(1));
myData.Add(Row(2));
myData.Add(Row(3));
return myData;
}
private List<string> Row(int p)
{
List<string> row = new List<string>();
for (int i = 0; i < 4; i++)
{
row.Add(string.Format("Column {0}/{1}", p, i));
}
return row;
}
private List<string> GetColDefsFromBackend()
{
List<string> cols = new List<string>();
cols.Add("Col1");
cols.Add("Col2");
cols.Add("Col3");
cols.Add("Col4");
return cols;
}

非常感谢你。这真的很有帮助,我花了一些时间试图理解这种转变背后的逻辑,作为一个新手,我最终得到了一个更小的代码:
private System.Data.DataTable CreateDataTable(List<string> columnDefinitions, List<List<string>> rows)
{
DataTable table = new DataTable();
foreach (string colDef in columnDefinitions)
{
DataColumn column;
column = new DataColumn();
column.DataType = typeof(string);
column.ColumnName = colDef;
table.Columns.Add(column);
}
for (int i = 0; i < rows[0].Count; i++)
{
table.Rows.Add(rows[0][i], rows[1][i], rows[2][i], rows[3][i], rows[4][i], rows[5][i], rows[6][i]);
}
return table;
}
private List<string> GetColDefsFromBackend()
{
List<string> cols = new List<string>();
cols.Add("Monday");
cols.Add("Tuesday");
cols.Add("Wednesday");
cols.Add("Thursday");
cols.Add("Friday");
cols.Add("Saturday");
cols.Add("Sunday");
return cols;
}

将List转换为数据表然后绑定。数组数组很难清楚地绑定。
