如何在texblock附近的DataGrid中插入图像

Question

我正在尝试在文本块附近插入图像。我有一系列球队，我想在他们的名字附近添加这支球队的盾牌。所以在WPF中我做了这个结构：

<DataGrid x:FieldModifier="public" x:Name="League_DataGrid" Grid.ColumnSpan="4" HorizontalAlignment="Left" Margin="10,368,0,0" VerticalAlignment="Top" Height="181" Width="676" AutoGenerateColumns="False">
        <DataGrid.Columns >
            <DataGridTextColumn Binding="{Binding Path = 'position'}" Header="Posizione" CanUserResize="False" />
            <DataGridTemplateColumn Header="Squadra">
                <DataGridTemplateColumn.CellTemplate>
                    <DataTemplate>
                        <StackPanel>
                            <Grid>
                                <TextBox Text="{Binding Path='name'}"/>
                            </Grid>
                            <Grid>
                                <Image Source="{Binding Path='logo'}"/>
                            </Grid>
                        </StackPanel>
                    </DataTemplate>
                </DataGridTemplateColumn.CellTemplate>
            </DataGridTemplateColumn>
            <DataGridTextColumn Binding="{Binding Path = 'points'}" Header="Punti" CanUserResize="true" MinWidth="150" MaxWidth="200" />
            <DataGridTextColumn Binding="{Binding Path = 'playedGames'}" Header="Partite Giocate" CanUserResize="False" />
            <DataGridTextColumn Binding="{Binding Path = 'goals'}" Header="Goal" CanUserResize="False" />
            <DataGridTextColumn Binding="{Binding Path = 'goalsAgainst'}" Header="Goal Subiti" CanUserResize="False" />
            <DataGridTextColumn Binding="{Binding Path = 'goalsDifference'}" Header="Differenza Reti" CanUserResize="False" />
        </DataGrid.Columns>
    </DataGrid>

因此，在c＃代码中，我创建了一个填充DataGrid的函数。

                int i=0;
                foreach (var classifica in leagueTable_Object.standing)
                {
                    MainWindow.AppWindow.League_DataGrid.Items.Add(new LeagueTable.Classifica
                    {
                        position = classifica.position,
                        name = classifica.teamName,
                        logo = SvgReader.Load(new MemoryStream(new System.Net.WebClient().DownloadData(Teams.team_struct[i].logo))),
                        playedGames = classifica.playedGames,
                        goals = classifica.goals,
                        goalsAgainst = classifica.goalsAgainst,
                        goalsDifference = classifica.goalDifference
                    });
                    i++;
                }

问题是当我执行这段代码时，我得到了这个例外：

XmlException was not managed.

我做错了什么？ 堆栈跟踪：
