Is it possible to set a datacolumn's datatype by using a string value?

[Benton]

Hi there,

I want to create some DataColumns using the following approach:

string datatype = "int";

DataColumn intCol = new DataCoulmn();
intCol.DataType = typeof(datatype);

string datatype = "string";

DataColumn strCol = new DataCoulmn();
strCol.DataType = typeof(datatype);

I know it doesn't work quite like this, but, is there a way to accomplish
what I am trying to do?

Best Regards,

-Benton

Hi,

try using Type.GetType(string typename);


string datatype = "System.String";

DataColumn strCol = new DataColumn();
strCol.DataType = Type.GetType(datatype);

You can also use

DataColumn strCol = new DataColumn();
strCol.DataType = typeof(string);

no quotes

Benton,


Design technically you are extending the DataColumn with something
like

public void SetDataType(string DataType as string)

or overloading the property DataType( which isnt possible).

Certainly the way to go if you are planning to add more functionality
or overrides to the DataColumn
