OdbcErrorCollection OdbcErrorCollection OdbcErrorCollection OdbcErrorCollection Class


收集 OdbcDataAdapter 生成的所有错误。Collects all errors generated by the OdbcDataAdapter. 此类不能被继承。This class cannot be inherited.

public ref class OdbcErrorCollection sealed : System::Collections::ICollection
public sealed class OdbcErrorCollection : System.Collections.ICollection
type OdbcErrorCollection = class
    interface ICollection
    interface IEnumerable
Public NotInheritable Class OdbcErrorCollection
Implements ICollection


下面的示例在OdbcError OdbcErrorCollection中显示每个。The following example displays each OdbcError within the OdbcErrorCollection.

public void DisplayOdbcErrorCollection(OdbcException exception) 
   for (int i=0; i < exception.Errors.Count; i++)
      MessageBox.Show("Index #" + i + "\n" +
             "Message: " + exception.Errors[i].Message + "\n" +
             "Native: " + exception.Errors[i].NativeError.ToString() + "\n" +
             "Source: " + exception.Errors[i].Source + "\n" +
             "SQL: " + exception.Errors[i].SQLState + "\n");
Public Sub DisplayOdbcErrorCollection(exception As OdbcException)
    Dim i As Integer

    For i = 0 To exception.Errors.Count - 1
        MessageBox.Show("Index #" + i.ToString() + ControlChars.Cr _
           + "Message: " + exception.Errors(i).Message + ControlChars.Cr _
           + "Native: " + exception.Errors(i).NativeError.ToString() + ControlChars.Cr _
           + "Source: " + exception.Errors(i).Source + ControlChars.Cr _
           + "SQL: " + exception.Errors(i).SQLState + ControlChars.Cr)
    Next i
End Sub


此类由OdbcException创建, 用于收集OdbcError类的实例。This class is created by OdbcException to collect instances of the OdbcError class. OdbcErrorCollection始终包含至少一个OdbcError类的实例。OdbcErrorCollection always contains at least one instance of the OdbcError class.
