我正在插入图像,这是我的代码:

void IFieldMergingCallback.ImageFieldMerging(ImageFieldMergingArgs e)
{
    if (this.mBuilder == null)
        this.mBuilder = new DocumentBuilder(e.Document);

    string filename = GetFilePath();
    if (!File.Exists(filename))
    {
        //todo insert text "<Image not found>" instead image
        this.mBuilder.MoveToField(e.Field, false);
        this.mBuilder.Write("<Image not found>");
        e.ImageFileName = string.Empty;
        return;
    }

    e.ImageFileName = filename;
}

如果图像不存在,我想插入文本"<Image not found>"。但是这段代码会引发错误Cannot load image from field '...'. The field contains data in unsupported format. Could not find file

我应该插入什么来修复我的错误?

这解决了我的问题。我只需要将字段删除到我的if语句中即可:

this.mBuilder.MoveToField(e.Field, false);
this.mBuilder.Write("<Image not found>");
e.Field.Remove();
return;
