问题
I am new to C#. I have rfc that returns data from SAP system as nested structure but when I'am fetching that data using:
IrfcTable table = rfc.getTable("exporting_parameter"); // et_customer
it returns only first inner structure only.
For example my exporting internal table for rfc is
et_customer that contains sub structure as follow:
gen_data
bank data
tax data
it returns value inside gen_data only.
How to get entire data?
回答1:
A couple of Extensions that may help. eg Convert from SAP structures to Other better known structures.
public static class SapToDataExtensionClass
{
public static Dictionary<string,string> ToDictionary(this IRfcStructure stru)
{
Dictionary<string,string> dict = new Dictionary<string, string>();
for (int i = 0; i < stru.Metadata.FieldCount; i++)
{
dict.Add(stru.Metadata[i].Name , stru.GetString(i) );
}
return dict;
}
public static DataTable GetDataTable(this IRfcTable i_Table)
{
DataTable dt = new DataTable();
dt.GetColumnsFromSapTable(i_Table);
dt.FillRowsFromSapTable(i_Table);
return dt;
}
public static void FillRowsFromSapTable(this DataTable i_DataTable, IRfcTable i_Table)
{
foreach (IRfcStructure tableRow in i_Table)
{
DataRow dr = i_DataTable.NewRow();
dr.ItemArray = tableRow.Select(structField => structField.GetValue()).ToArray();
i_DataTable.Rows.Add(dr);
}
}
public static void GetColumnsFromSapTable(this DataTable i_DataTable, IRfcTable i_SapTable)
{
var DataColumnsArr = i_SapTable.Metadata.LineType.CreateStructure().ToList().Select
(structField => new DataColumn(structField.Metadata.Name)).ToArray();
i_DataTable.Columns.AddRange(DataColumnsArr);
}
}
