C# 成员'；XmlSchema'；找不到

谁能解释一下下面的错误是什么？我是asp.net编码新手

this.dataSet1.DataSetName = "DataSet";
this.dataSet1.SchemaSerializationMode = System.Data.SchemaSerializationMode.IncludeSchema;

此问题发生在我创建devExpress报表类文件时。 是因为文件由

this.dataSet1.DataSetName = "DataSet";
this.dataSet1.SchemaSerializationMode = System.Data.SchemaSerializationMode.IncludeSchema;

---

描述：执行当前web请求期间发生未处理的异常。请查看堆栈跟踪以了解有关错误的更多信息以及错误在代码中的起源

this.dataSet1.DataSetName = "DataSet";
this.dataSet1.SchemaSerializationMode = System.Data.SchemaSerializationMode.IncludeSchema;

异常详细信息：System.Runtime.Serialization.SerializationException:未找到成员“XmlSchema”

this.dataSet1.DataSetName = "DataSet";
this.dataSet1.SchemaSerializationMode = System.Data.SchemaSerializationMode.IncludeSchema;

*错误在第51行

this.dataSet1.DataSetName = "DataSet";
this.dataSet1.SchemaSerializationMode = System.Data.SchemaSerializationMode.IncludeSchema;

**Line 51:         string strSchema = ((string)(info.GetValue("XmlSchema", typeof(string))));**
Line 52:         if ((this.DetermineSchemaSerializationMode(info, context) == global::System.Data.SchemaSerializationMode.IncludeSchema)) {
Line 53:             global::System.Data.DataSet ds = new global::System.Data.DataSet();

你需要提供更多的信息…例如，

信息的类型是什么？

…是的，就像那是什么代码？对不起，内容已更新。你想在这里做什么？我试图加载我的默认页面，但它遇到了此错误
