确定指定的对象是否有效。

重载

TryValidateObject(Object, ValidationContext, ICollection<ValidationResult>)	通过使用验证上下文和验证结果集合，确定指定的对象是否有效。
TryValidateObject(Object, ValidationContext, ICollection<ValidationResult>, Boolean)	通过使用验证上下文、验证结果集合和用于指定是否验证所有属性的值，确定指定的对象是否有效。

Source:: Validator.cs

通过使用验证上下文和验证结果集合，确定指定的对象是否有效。

public:
 static bool TryValidateObject(System::Object ^ instance, System::ComponentModel::DataAnnotations::ValidationContext ^ validationContext, System::Collections::Generic::ICollection<System::ComponentModel::DataAnnotations::ValidationResult ^> ^ validationResults);

public static bool TryValidateObject (object instance, System.ComponentModel.DataAnnotations.ValidationContext validationContext, System.Collections.Generic.ICollection<System.ComponentModel.DataAnnotations.ValidationResult> validationResults);

public static bool TryValidateObject (object instance, System.ComponentModel.DataAnnotations.ValidationContext validationContext, System.Collections.Generic.ICollection<System.ComponentModel.DataAnnotations.ValidationResult>? validationResults);

static member TryValidateObject : obj * System.ComponentModel.DataAnnotations.ValidationContext * System.Collections.Generic.ICollection<System.ComponentModel.DataAnnotations.ValidationResult> -> bool

Public Shared Function TryValidateObject (instance As Object, validationContext As ValidationContext, validationResults As ICollection(Of ValidationResult)) As Boolean

参数

instance: Object

要验证的对象。

validationContext: ValidationContext

用于描述要验证的对象的上下文。

validationResults: ICollection<ValidationResult>

用于包含每个失败的验证的集合。

Boolean

如果对象有效，则为 true；否则为 false。

例外

ArgumentNullException

instance 为 null。

ArgumentException

instance 与 validationContext 上的 ObjectInstance 不匹配。

注解

此方法计算附加到对象类型的每个 ValidationAttribute 实例。它还检查是否提供了标记的每个 RequiredAttribute 属性。它不会以递归方式验证对象的属性值。
