我有一个带有电子邮件的DataTables。在LDAP上我有Userdata。现在我想根据EmailAdress增加DataTable。
myDataTable.Columns.Add(new DataColumn("LDAP_Data"));
foreach(DataRow row in modiTable.Rows)
{
string myLDAPData = DoLDAPAction(row.Field<string>("EMAIL"));
//how to insert to myDataTable > LDAP_Data
}
如何将新数据从LDAP插入新列?

如果向DataTable
添加行,则必须添加与您的表匹配的行。这就是为什么如果你拨打DataTable.Add()
,你会回来的。
这是一个如何添加新行的示例:
static void Main(string[] args)
{
DataTable dt = new DataTable(); // Create a example-DataTable
dt.Columns.Add(new DataColumn() { ColumnName = "Name", DataType = typeof(string) }); // Add some columns
dt.Columns.Add(new DataColumn() { ColumnName = "Id", DataType = typeof(int) });
// Let's fill the table with some rows
for (int i = 0; i < 20; i++) // Add 20 Rows
{
DataRow row = dt.Rows.Add(); // Generate a row
row["Id"] = i; // Fill in some data to the row. We can access the columns which we added.
row["Name"] = i.ToString();
}
// Let's see what we got.
for (int i = 0; i < dt.Columns.Count; i++) // Loop through all columns
{
Console.Write(dt.Columns[i].ColumnName + ";"); // Write the ColunName to the console with a ';' a seperator.
}
Console.WriteLine();
foreach (DataRow r in dt.Rows) // Generic looping through DataTable
{
for (int i = 0; i < dt.Columns.Count; i++) // Loop through all columns
{
Console.Write(r[i] + ";");
}
Console.WriteLine();
}
}
