Item is conditionally case-sensitive when it searches for column names. For example, if one DataColumn is named "mydatacolumn" and another is named "Mydatacolumn", a string used to search for one of the columns is regarded as case-sensitive. However, if "mydatacolumn" exists and "Mydatacolumn" does not, the search string is regarded as case-insensitive.
privatevoid PrintDataType(DataTable table)
// Get the DataColumnCollection from a DataTable in a DataSet.
DataColumnCollection columns = table.Columns;
// Print the column's data type.
