This will populate object properties with values from a DataRow. The DataTable column names must match the property names and types of the target class.

Example:

DataTable dt = new DataTable();
dt.Columns.Add("TestString", typeof(string));
dt.Columns.Add("TestBool", typeof(bool));
dt.Columns.Add("TestInt", typeof(int));
dt.Columns.Add("TestDouble", typeof(double));
dt.Columns.Add("TestDecimal", typeof(decimal));
dt.Columns.Add("TestFloat", typeof(string));

DataRow dr = dt.NewRow();
dr["TestString"] = "Hello";
dr["TestBool"] = false;
dr["TestInt"] = DBNull.Value;
dr["TestDouble"] =4.56;
dr["TestDecimal"] = 7.89m;
dr["TestFloat"] = "3.14f";
dt.Rows.Add(dr);

TestClass tc = new TestClass();
dr.AssignObjectValue(tc);

class TestClass
{
public string TestString { get; set; }
public bool? TestBool { get; set; }
public int? TestInt { get; set; }
public double TestDouble { get; set; }
public decimal TestDecimal { get; set; }
public float TestFloat { get; set; }
}
