Converting Class Array to DataTable : C#

Methods to Convert Class Array to DataTable

private static void FillData(PropertyInfo[] propertyInfo, DataTable dataTable, Object objectSource)

{

DataRow dataRow = dataTable.NewRow();

foreach (PropertyInfo pi in propertyInfo)

dataRow[pi.Name] = pi.GetValue(objectSource, null);

dataTable.Rows.Add(dataRow);

}

private static DataTable CreateDataTable(PropertyInfo[] propertyInfo)

{

DataTable dataTable = new DataTable();

DataColumn dataColumn = null;

foreach (PropertyInfo pi in propertyInfo)

{

dataColumn = new DataColumn();

dataColumn.ColumnName = pi.Name;

dataColumn.DataType = pi.PropertyType;

dataTable.Columns.Add(dataColumn);

}

return dataTable;

}

public static DataTable ConvertToDataTable(Object[] array)

{

PropertyInfo[] propertyInfo = array.GetType().GetElementType().GetProperties();

DataTable dataTable = CreateDataTable(propertyInfo);

if (array.Length != 0)

{

foreach (object o in array)

FillData(propertyInfo, dataTable, o);

}

return dataTable;

}

Ramdom Password Generation : Using C#

The following C# code will generate a random number without repeating character

public static string GetRandomPassword(int passwordLength)

{

string allowedChars = "$%#@!*abcdefghijklmnopqrstuvwxyz1234567890?~ABCDEFGHIJKLMNOPQRSTUVWXYZ^&";

string newPassword = "";

Random randomNumber = new Random();

for (int i = 0; i <>

{

int charIndex = randomNumber.Next(allowedChars.Length);

//Don't Allow Repetation of Characters

if (!newPassword.Contains(allowedChars[charIndex] + ""))

newPassword += allowedChars[charIndex];

else

i--;

}

return newPassword;

}

Print a number in Currency Format

To print a number in currency (dollar - $) format, use the following code

Create an object for NumberFormatInfo Class in the class level

protected System.Globalization.NumberFormatInfo nfi = null;

Then create an instance for the object and assign the CurrencySymbol and CurrencyDecimalDigits as below in the Page_Load Event

nfi = new System.Globalization.NumberFormatInfo();

nfi.CurrencyDecimalDigits = 0;

nfi.CurrencySymbol = "$";

In the ASPX page to print the number in currency format use the following code

<%#String.Format(nfi,"{0:C}", Convert.ToDecimal (DataBinder.Eval(Container.DataItem,"Price"))) %>
