All,

I've been using GetSchemaTable() to retrieve the attributes for columns in a SQL table.

I was wondering how to determine the specific datatype of the column.
DataTable Attributes = DR.GetSchemaTable();

for(int i;i < Attributes.Rows.Count; i++)
{
   Att[i,0] = Attributes.Rows[i]["ColumnName"];
   Att[i,1] = Attributes.Rows[i]["AllowDBNull"];
   Att[i,2] = Attributes.Rows[i]["DataType"];
}
If I examine Attributes.Rows[i]["DataType"] in the watch window I see {System.RuntimeType}. Below it I see the plus sign in the square with
System.Type {"System.String"}

How can I readily determine that Attributes.Rows[i]["DataType"] = "String" ?

I tried Reflection with Type t = Attributes.Rows[i]["DataType"].GetType(); But that did not further the crusade either.

This is probably simple, but I do not see the tree in the forest.
TIA,
Doug
