SqlErrorCollection Class

Collects all errors generated by the .NET Framework Data Provider for SQL Server. This class cannot be inherited.

Namespace: System.Data.SqlClient
Assembly: System.Data (in system.data.dll)

[SerializableAttribute] 
public sealed class SqlErrorCollection : ICollection, IEnumerable
/** @attribute SerializableAttribute() */ 
public final class SqlErrorCollection implements ICollection, IEnumerable
SerializableAttribute 
public final class SqlErrorCollection implements ICollection, IEnumerable

This class is created by SqlException to collect instances of the SqlError class. SqlErrorCollection always contains at least one instance of the SqlError class.

The following example displays each SqlError within the SqlErrorCollection collection.

public static void ShowSqlException(string connectionString)
{
    string queryString = "EXECUTE NonExistantStoredProcedure";
    
    using (SqlConnection connection = new SqlConnection(connectionString))
    {
        SqlCommand command = new SqlCommand(queryString, connection);
        try
        {
            command.Connection.Open();
            command.ExecuteNonQuery();
        
        catch (SqlException ex)
        {
            DisplaySqlErrors(ex);
        
    


private static void DisplaySqlErrors(SqlException exception)
{
    for (int i = 0; i < exception.Errors.Count; i++)
    {
        Console.WriteLine("Index #" + i + "\n" +
            "Error: " + exception.Errors[i].ToString() + "\n");
    
    Console.ReadLine();
